.NET Core : IFileProvider.GetDirectoryContents recursive not working

I would like to scan a directory ("C:/test") and get all files .pdf recursively
I create a provider like this :
IFileProvider provider = new PhysicalFileProvider("C:/test"); // using config in my code and also tried with "C:/test/"
I placed some pdf in directories and subdirectories
There's a file with this path : C:/test/pdf59.pdf
Another with C:/test/testComplexe/pdf59.pdf
Where I try these lines, they all return "NotFoundDirectoryException" :
provider.getDirectoryContents(#"**")
provider.getDirectoryContents(#"*")
provider.getDirectoryContents(#"*.*")
provider.getDirectoryContents(#"**.*")
provider.getDirectoryContents(#"pdf59.pdf")
provider.getDirectoryContents(#"*.pdf")
Exception this line :
provider.getDirectoryContents(#"testComplexe")
How could i query these recursive directories and files ? Thank you

You can write your own recursive function.
var files = new List<IFileInfo>();
GetFiles("C:/Tests", files);
private void GetFiles(string path, ICollection<IFileInfo> files)
{
IFileProvider provider = new PhysicalFileProvider(path);
var contents = provider.GetDirectoryContents("");
foreach (var content in contents)
{
if (!content.IsDirectory && content.Name.ToLower().EndsWith(".pdf"))
{
files.Add(content);
}
else
{
GetFiles(content.PhysicalPath, files);
}
}
}

For my future self (and others) to copy-paste...
public static class Demo
{
public static void FindPdfs()
{
var provider = new PhysicalFileProvider("c:\\temp");
var pdfs = new List<IFileInfo>();
provider.FindFiles(
directory: "/",
match: file => file.Name.EndsWith(".pdf"),
process: pdfs.Add,
recursive: true);
foreach (var pdf in pdfs)
{
using (var stream = pdf.CreateReadStream())
{
// etc...
}
}
}
}

{
/// <summary>

public static int FindFiles(this IFileProvider provider, string directory, Predicate<IFileInfo> match, Action<IFileInfo> process, bool recursive = false)
{
var dirsToSearch = new Stack<string>();
dirsToSearch.Push(directory);
var count = 0;
while (dirsToSearch.Count > 0)
{
var dir = dirsToSearch.Pop();
foreach (var file in provider.GetDirectoryContents(dir))
{
if (file.IsDirectory)
{
if (!recursive)
continue;
var relPath = Path.Join(dir, file.Name);
dirsToSearch.Push(relPath);
}
else
{
if (!match(file))
continue;
process(file);
count++;
}
}
}
return count;
}
}

This is the simplest version if you just want a list of IFileInfo objects. It uses an extension method. Assumes you already have a IFileProvider, such as one that has been injected.
var files = FileProvider.GetRecursiveFiles("/images").ToArray();
 
using Microsoft.Extensions.FileProviders;
using System.Collections.Generic;
using System.IO;
public static class FileProviderExtensions
{
public static IEnumerable<IFileInfo> GetRecursiveFiles(this IFileProvider fileProvider, string path, bool includeDirectories = true)
{
var directoryContents = fileProvider.GetDirectoryContents(path);
foreach (var file in directoryContents)
{
if (file.IsDirectory)
{
if (includeDirectories)
{
yield return file;
}
// recursively call GetFiles and return each one
// file.Name is the directory name alone (eg. images)
foreach (var f in fileProvider.GetRecursiveFiles(Path.Combine(path, file.Name), includeDirectories))
{
yield return f;
}
}
else
{
// return file
yield return file;
}
}
}
}

To get the content of your root folder ("C:/test/"), use the provider this way :
var contents = provider.getDirectoryContents("")
Then, you have to enumerate results in contents, and do what ever you want with each one.

Recursively get all children of SAP Gui Session in c#

I am looking to loop through all SAP GuiComponents in c# but am struggling to get all the children of children of a gui session.
This is what I have so far (initially passing session.ActiveWindow.Children to nodes):
private void IterateFindIDByNAme(GuiComponentCollection nodes, string searchstring)
{
if (foundID == "")
{
foreach (GuiComponent node in (GuiComponentCollection)nodes)
{
var comp = node;
if (comp.Name.Contains(searchstring))
foundID = comp.Id;
else
{
try
{
FindIDByNAme((GuiComponentCollection)node, searchstring);
}
catch { }
}
}
}
}
Its able to get all the child elements of session.ActiveWindow but when trying to cast all the children to GuiComponentCollections its falling over.
This would be irrelevant if I could use the FindByName function but for some reason it is not working on the SAP screen i am currently working on (it does work on others, not sure why).
The ID of the field is:
wnd[0]/usr/subBCA_SUB_HEADER:SAPLBANK_BDT_CTRL:0100/subSUBS_DETAIL:SAPLBUSS:0028/ssubGENSUB:SAPLBUSS:4038/subA01P02:SAPLBCA_DYN_CN_CNMANO:0002/ctxtBCA_DYN_CONTRACT_ORGENTRY-ORGUNIT
and the function I am trying is:
((GuiTextField)session.FindByName("BCA_DYN_CONTRACT_ORGENTRY-ORGUNIT", "GuiTextField")).Text = "Test";
The findbyid works fine, but not findbyname?
I know this is 2 questions, but kind of related.

ctxtBCA_DYN_CONTRACT_ORGENTRY-ORGUNIT
The type of the control is a GuiCTextField not GuiTextField:
session.FindByName("BCA_DYN_CONTRACT_ORGENTRY-ORGUNIT", "GuiCTextField")
Sample Code :
public DateTime? GetModificationDate(int employeeID)
{
var session = SapHelper.GetActiveSession();
Console.WriteLine("Recherche de la measure [A5 ou A6] avec un motif 90...");
var window = session.BeginTransaction("PA20", "Afficher données de base personnel");
window.FindByName<GuiCTextField>("RP50G-PERNR").Text = employeeID.ToString();
window.FindByName<GuiCTextField>("RP50G-CHOIC").Text = "Mesures (0000)";
window.FindByName<GuiCTextField>("RP50G-SUBTY").Text = null;
window.FindByName<GuiButton>("btn[20]").Press(); // list view
if (window.Text == "Afficher données de base personnel")

Console.WriteLine(">> " + window.FindByName<GuiStatusbar>("sbar").Text);
return null;

EDIT: The link to the LINQPad script mentioned in comment below no longer works. I have re-uploaded it here.
This script helps you to browse SAP GUI:
List control type, name, id, content
List properties and methods
Highlight control
Generate selector : .FindByName<GuiTableControl>("MP000000TC3000")

In case anyone wants to know how to get child elements of any gui component (this will simply write all ids to the console):
private void LoopAllElements(GuiComponentCollection nodes)
{
foreach (GuiComponent node in (GuiComponentCollection)nodes)
{
Console.WriteLine(node.Id);
if (node.ContainerType)
{
var children = ((node as dynamic).Children as GuiComponentCollection);
LoopAllElements(children);
}
}
}
This will loop through all child elements of any GUIComponentCollection you pass to it such as
LoopAllElements(session.Children)
There is probably a better linq way of doing this but this should get you started.
Please also check out this gist created by Xiaoy312 https://gist.github.com/Xiaoy312/a1424bd34acae92554105b27b0c80971
this has a lot of useful functions to debug your current sap session which i have found extremely useful.
You can either view the code as it has a number of functions you can use such as improved findbyid and findbyname or run it in linqpad https://www.linqpad.net/Download.aspx which will allow you to interogate the current SAP session.

If I understood correctly we have to manually start SAP Logon to make line below working:
var rot = new CSapROTWrapper().GetROTEntry("SAPGUI");
Am I right?
If so maybe someone can explain me why at the line:
var app = (GuiApplication)rot.GetType().InvokeMember("GetScriptingEngine", BindingFlags.InvokeMethod, null, rot, null);
I am getting exception:
An exception of type 'System.Runtime.InteropServices.COMException'
occurred in System.Dynamic.dll but was not handled in user code
Additional information: Error loading type library/DLL. (Exception
from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRARY))
I've already tried to change target platform from Any CPU to x86 and x64 and didn't have success in resolving this problem.
But when I run SAPGUI using following script:
var SapGuiApp = new GuiApplication();
string development = "Development ERP System";
var connection = SapGuiApp.OpenConnection(development);
instead of running SAP Logon manually described above problem is not reproducing.
But in this case I have other problem: GUI is different and for second option GUI looks corrupted - some of GUI controls are not displayed (please see screenshot). Please give me advice what can be wrong? Thank you in advance
UPDATE: I found solution that solves issue described below. You have to use object instead of var while you are trying to get session connection:
CSapROTWrapper sapROTWrapper = new CSapROTWrapper();
object rot = sapROTWrapper.GetROTEntry("SAPGUI");
object engine = rot.GetType().InvokeMember("GetScriptingEngine", System.Reflection.BindingFlags.InvokeMethod, null, rot, null);
GuiConnection connection = (engine as GuiApplication).OpenConnection(connectionName);
GuiSession session = connection.Children.ElementAt(0) as GuiSession;

Sugar CRM 6.5.14 - Calling REST API with C#

Amazingly low on doco when it comes to rest api. Can anyone give me a working example of Sugar CRM REST calls using C#?
I was trying out SugarSharp but it's just listing the services and not coming up with Data(null)

Appreciate this is an old question but for anyone else that comes across it, took me a while to get it all working with creating and updating relationships being the toughest to fathom.
Here is part of a wrapper class I wrote around the v4_1 rest api, hope it helps:-
public void Login()
{
object loginData = new
{
user_auth = new
{
user_name = Username,
password = CalculateMD5Hash(Password)
}
};
string jsonData = CreateFormattedPostRequest("login", loginData);
var request = GetRestRequest(jsonData, "POST");
var loginResponse = GetRestResponseByType<LoginResponse>(request);
if (string.IsNullOrEmpty(loginResponse.id))
{
throw new SugarException(string.Concat("Authorisation Failed for user: {0}, did not retrieve access token", Username));
}
SessionID = loginResponse.id;
}
Format the request:-
private string CreateFormattedPostRequest(string method, object data)
{
StringBuilder buffer = new StringBuilder();
using (StringWriter writer = new StringWriter(buffer))
{
serializer.Serialize(data, buffer);
}
string result = "method=" + method;
result += "&input_type=JSON&response_type=JSON&rest_data=" + buffer.ToString();
return result;
}
And finally get the response:-
private object GetRestResponseAsObject(HttpWebRequest request)
{
using (var response = (HttpWebResponse)request.GetResponse())
{
using (Stream input = response.GetResponseStream())
{
StreamReader reader = new StreamReader(input);
string buffer = reader.ReadToEnd();
var responseObj = serializer.DeserializeObject(buffer);
return responseObj;
}
}
}
And here is an example call to the set_entry method:-
/// <summary>
/// Creates or Updates a single bean, for update ensure that the name_value_list contains the ID of the record
/// name_value_lists - Dictionary where the keys of the are the SugarBean attributes (columns), the values of the array are the values the attributes should have.
/// </summary>
/// <param name="module">Module to update i.e Account</param>
/// <param name="record">key value pair object of record, include ID for update</param>
/// <returns>Returns the updated or created Bean ID</returns>
public string CreateUpdateBean(string module, object record)
{
var parameters = new Dictionary<string, object>();
parameters.Add("session", SessionID);
parameters.Add("module_name", module);
parameters.Add("name_value_list", record);
parameters.Add("track_view", false);
string jsonData = CreateFormattedPostRequest("set_entry", parameters);
var request = GetRestRequest(jsonData, "POST");
var result = GetRestResponseByType<object>(request);
return result.ToString();
}

For calling rest api SugarCRM/SuiteCRM with c#, you can use SugarRestSharp
Example for create Account:
var client = new SugarRestClient(TestAccount.Url, TestAccount.Username, TestAccount.Password);
Account insertAccount = AccountsModule.GetTestAccount();
// -------------------Create Account-------------------
SugarRestResponse response = AccountsModule.CreateAccount(client, insertAccount);
Assert.NotNull(response);
Assert.Equal(response.StatusCode, HttpStatusCode.OK);
string insertId = (response.Data == null) ? string.Empty : response.Data.ToString();
Assert.NotNull(insertId);
Assert.NotEmpty(insertId);
// -------------------End Create Account-------------------

The remote host closed the connection. The error code is 0x800703E3

I am currently trying to generate a CSV using nhibernate. This error does not occur on my development enviroment but it does on the live site that it's being used on. I have tried fiddling with time out's but this does not seem to have any effect as it's timing out way before it should. The timing is completely random, sometimes it'll be 3 seconds before it times out the next it will be 10 seconds. There doesn't seem to be any real consistancy in the timing.

How can you change Network settings (IP Address, DNS, WINS, Host Name) with code in C#

I am developing a wizard for a machine that is to be used as a backup of other machines. When it replaces an existing machine, it needs to set its IP address, DNS, WINS, and host name to match the machine being replaced.
Is there a library in .net (C#) which allows me to do this programatically?
There are multiple NICs, each which need to be set individually.
EDIT
Thank you TimothyP for your example. It got me moving on the right track and the quick reply was awesome.
Thanks balexandre. Your code is perfect. I was in a rush and had already adapted the example TimothyP linked to, but I would have loved to have had your code sooner.
I've also developed a routine using similar techniques for changing the computer name. I'll post it in the future so subscribe to this questions RSS feed if you want to be informed of the update. I may get it up later today or on Monday after a bit of cleanup.

Refactored the code from balexandre a little so objects gets disposed and the new language features of C# 3.5+ are used (Linq, var, etc). Also renamed the variables to more meaningful names. I also merged some of the functions to be able to do more configuration with less WMI interaction. I removed the WINS code as I don't need to configure WINS anymore. Feel free to add the WINS code if you need it.
For the case anybody likes to use the refactored/modernized code I put it back into the community here.

I like the WMILinq solution. While not exactly the solution to your problem, find below a taste of it :
using (WmiContext context = new WmiContext(#"\\.")) {
context.ManagementScope.Options.Impersonation = ImpersonationLevel.Impersonate;
context.Log = Console.Out;
var dnss = from nic in context.Source<Win32_NetworkAdapterConfiguration>()
where nic.IPEnabled
select nic;
var ips = from s in dnss.SelectMany(dns => dns.DNSServerSearchOrder)
select IPAddress.Parse(s);
}

A far more clear solution is to use the command netsh to change the IP (or setting it back to DHCP)
netsh interface ip set address "Local Area Connection" static 192.168.0.10 255.255.255.0
Where "Local Area Connection" is the name of the network adapter. You could find it in the windows Network Connections, sometimes it is simply named "Ethernet".
Here are two methods to set the IP and also to set the IP back to DHCP "Obtain an IP address automatically"
public bool SetIP(string networkInterfaceName, string ipAddress, string subnetMask, string gateway = null)
{
var networkInterface = NetworkInterface.GetAllNetworkInterfaces().FirstOrDefault(nw => nw.Name == networkInterfaceName);
var ipProperties = networkInterface.GetIPProperties();
var ipInfo = ipProperties.UnicastAddresses.FirstOrDefault(ip => ip.Address.AddressFamily == AddressFamily.InterNetwork);
var currentIPaddress = ipInfo.Address.ToString();
var currentSubnetMask = ipInfo.IPv4Mask.ToString();
var isDHCPenabled = ipProperties.GetIPv4Properties().IsDhcpEnabled;
if (!isDHCPenabled && currentIPaddress == ipAddress && currentSubnetMask == subnetMask)
return true; // no change necessary
var process = new Process
{
StartInfo = new ProcessStartInfo("netsh", $"interface ip set address \"{networkInterfaceName}\" static {ipAddress} {subnetMask}" + (string.IsNullOrWhiteSpace(gateway) ? "" : $"{gateway} 1")) { Verb = "runas" }
};
process.Start();
var successful = process.ExitCode == 0;
process.Dispose();
return successful;
}
public bool SetDHCP(string networkInterfaceName)
{
var networkInterface = NetworkInterface.GetAllNetworkInterfaces().FirstOrDefault(nw => nw.Name == networkInterfaceName);
var ipProperties = networkInterface.GetIPProperties();
var isDHCPenabled = ipProperties.GetIPv4Properties().IsDhcpEnabled;
if (isDHCPenabled)
return true; // no change necessary
var process = new Process
{
StartInfo = new ProcessStartInfo("netsh", $"interface ip set address \"{networkInterfaceName}\" dhcp") { Verb = "runas" }
};
process.Start();
var successful = process.ExitCode == 0;
process.Dispose();
return successful;
}

A slightly more concise example that builds on top of the other answers here. I leveraged the code generation that is shipped with Visual Studio to remove most of the extra invocation code and replaced it with typed objects instead.

{
