Given path format not supported c# - c#

I get this exception when trying to perform an XSLT transformation with C#:
Exception: System.NotSupportedException: The given path's format is not supported.

i try to use Path.Combine(); but give me the same case
How can i solve this ?

Unfortunately, it was not clear from your question that you are using Silverlight (or at least some platform that somehow triggers this method)). When I started searching for QuickDemand, it turned out that this is only called in SilverLight (or similar?) environments, so I am rewriting my answer with that in mind.
at System.Security.Permissions.FileIOPermission.QuickDemand
This error is caused by this block of code in the reference source. As can be seen there, if the path contains a colon above second position, it is considered invalid.
In your code above this isn't shown, but since this is the only place in the reference source where this specific error is thrown, I am going to assume that the real code you have (possibly any of the xsl:includes in the XSLT) is containing a colon at some position other than the second position.
Either way, if this doesn't help, go to the Exceptions screen and check the NotSupportedException and in the Debug window uncheck the "Just my code" and check the "Enable .NET framework source stepping". That way, you can break at the position where the error is thrown and use IntelliSense and the debug windows to find out the context (i.e. the actual path) that is causing this error.
Also, from my previous post, if this doesn't help:
Try your code with a minimal XSLT (this is vital!)
Once you have that running, add an xsl:include
Once you have that running, add a document (if you use that, in addition, enable it in the settings)
Once you have that running... well, you get the drift

ArgumentException : "the path is not of a legal form" when using the CallerFilePath attribute in a script

Context
I am trying to run a C# script (.csx file) programmatically from a program I will call ScriptRunner.exe here and that I wrote myself (because csi.exe doesn't output what I want).ScriptRunner.exe is a simple console application and its most interesting feature is to have the following line :
var state = await CSharpScript.RunAsync<int>(script, referencesAndUsings, globalArgs);
ScriptRunner.exe works great ! However...
Problem
The moment my script contains the following line :
static string GetCurrentFileName([System.Runtime.CompilerServices.CallerFilePath] string fileName = null) { return fileName; }
and in particular [System.Runtime.CompilerServices.CallerFilePath], I get an ArgumentException : "the path is not of a legal form" ; note that the latter doesn't appear if I use the same line from a C# Interactive through a #load command - which correctly shows the path of my .csx file.
Investigated elements until now
The stacktrace shows at System.IO.Path.LegacyNormalizePath(String path, Boolean fullCheck, Int32 maxPathLength, Boolean expandShortPaths)
I checked what seems to be the implementation
I checked by hand the path of my csx file ; there's no invalid path characters in the path to my csx, and no wildcards in it either.
I checked there was no reference issue with mscorlib
Maybe something is missing in the ScriptOptions (referencesAndUsings in my first sample code), I looked at it but... I don't seem to understand everything well enough
The way I created my ScriptOptions ("referencesAndUsings") looks like the following:
var myOptions = ScriptOptions.Default;
myOptions.AddReferences(new List<string>() { ... });
myOptions.AddImports(new List<string>() { ... });
This is the documentation for the CallerFilePath attribute
This is the documentaiont for the concept of Caller Information
What really saddens me is that it works in C# Interactive.
Question
Does anyone know why it wouldn't want to work when interpreted by my ScriptRunner.exe ; and how to make it work ?
In
var state = await CSharpScript.RunAsync<int>(script, referencesAndUsings, globalArgs);
script is the script itself (the contents of the csx file). As such it has no path. CSharpScript knows nothing about the path of your csx file. When you call GetCurrentFileName from within the script, there is no path information.
You need to specify a FilePath in ScriptOptions using WithFilePath(csxFilePath)

Getting the calling function in a custom ExcelDNA exception handler without MacroType

I'm aware that there is the method shown in the ErrorHAndler.dna example:
private object ErrorHandler(object exceptionObject)
{
ExcelReference caller = (ExcelReference)XlCall.Excel(XlCall.xlfCaller);
// Calling reftext here requires all functions to be marked IsMacroType=true, which is undesirable.
// A better plan would be to build the reference text oneself, using the RowFirst / ColumnFirst info
// Not sure where to find the SheetName then....
string callingName = (string)XlCall.Excel(XlCall.xlfReftext, caller, true);
[...]
}
But has anyone determined how the issue described in the comment might be resolved? I.e. is there a way to do this without setting IsMacroType=true?
You don't need IsMacroType=true to get the caller (the first line in your sample works fine without it). As the comment in your sample indicates, if you want to build a text description for the range, you need to build it yourself from the Row/Column info in the ExcelReference. You can get the sheet name with a call to XlCall.Excel(XlCall.xlSheetNm, caller).

Creating new theme in orchard with codegeneration module

I was following the documentation on this OrchardProject.net link. I opened have activated the CodeGeneration module and opened the command prompt at the root of the project (Orchard.Web) and write "bin/Orchard.exe" for running the commands. Till then everything is fine. Now when I try to run the following command, it gives me the below exception. The command is:
codegen theme mishrajiTheme /BasedOn:TheThemeMachine /CreateProject:true /IncludeInSolution:true
Below is the output of the command.
Creating Theme

What I am doing wrong here or It is a bug in Orchard code generation module.
Please guide. I am using Orchard 1.10 version.
I solved this problem by changing the CodeGenerationCommands Class in line 434 in Orchard 1.10. the line is :
solutionText = solutionText.Insert(solutionText.LastIndexOf("EndProject\r\n"), projectReference);
to this :
solutionText = solutionText.Insert(solutionText.LastIndexOf("EndProject\n"), projectReference);
i don't know why by \r\n can not found the final EndProject and by changing that to \n it works fine
The line of code in question that has failed is this:
solutionText = solutionText.Insert(solutionText
.LastIndexOf("EndProject\r\n"),projectReference)
.Replace("GlobalSection(ProjectConfigurationPlatforms) = postSolution\r\n",
projectConfiguationPlatforms);
If solutionText.LastIndexOf("EndProject\r\n") doesn't find anything it will return -1 - see the MSDN docs here.
It looks like that is then being passed to the string.Insert which is an invalid out of index.
The only thing that I can think is that your git client or however you got your hands on the orchard source has somehow changed the line endings in the file so it can't find the \r\n.
I'm guessing you are from the indian subcontinent, is your OS running a non-english language? I don't think that the .sln file localises fields like EndProject and I don't think Windows varies its newline character representation but something is going wrong here.
Workaround Solution
This is the very last thing that the codegen theme command does, it has created everything else and just failed to add your project into the Orchard.sln. To get moving right now you can just add it to your solution:
In visual studio, open solution explorer window
Right click on your Themes solution folder
Click Add | Existing project
Navigate to the folder and select your new theme
Potential Bug
It seems like there could be a bug here. Would you be willing to post your .sln file to me via email so I can investigate it further?

C#: ArgumentException when calling System.Management.Automation.Runspaces.RunspaceFactory.CreateRunspace()

I am in a bit of a strange situation. I have been given a fairly large suite of PowerShell modules and functions, and it is my job to tie these together into an executable. The requirements state that this must be a single, standalone executable with no installer and .net 3.5 may be the only dependency. The Windows Management Framework is not an exception and cannot be assumed to exist on the machine. To get around this, I have added System.Management.Automation as a reference and made it an embedded resource, along with all of the PowerShell module files, and load them from reflection at runtime. This seems to work OK, but I have some errors that I cannot seem to figure out and think it might have something to do with this system.
So Here is the issue: When I start to initialize things to run the PowerShell command, I get a strange error that I can't seem to control.
Here is the code:
public static void RunCommand(object objcommand)
{
//create a script block for toolbox once, get the embeded resource, convert from byte array to string, make scriptblock from string
ScriptBlock toolbox = System.Management.Automation.ScriptBlock.Create(System.Text.Encoding.Default.GetString(Properties.Resources.toolbox));
string command = (string)objcommand;
//get the module name
string modname = options.Commands[command]["module"];
//get the module from the embeded resources, convert to string, convert to scriptblock
var module = System.Management.Automation.ScriptBlock.Create(new System.IO.StreamReader(myasm.GetManifestResourceStream("piramids.Resources." + modname + ".psm1")).ReadToEnd());
using (var powerShell = PowerShell.Create())
{
System.Management.Automation.Runspaces.Runspace rs = System.Management.Automation.Runspaces.RunspaceFactory.CreateRunspace(); //i think this line triggers the exception
rs.Open();
powerShell.Runspace = rs;
//make the necesary powershell modules of the command availible
powerShell.AddCommand("new-module").AddParameter("ScriptBlock", toolbox).Invoke();
powerShell.AddCommand("new-module").AddParameter("ScriptBlock", module).Invoke();
//if inethistory, make dlls availible
if (modname.Equals("inethistory"))
{
powerShell.AddCommand("add-type").AddParameter("Path", sqldll).Invoke();
powerShell.AddCommand("add-type").AddParameter("Path", esentdll).Invoke();
}
ICollection<PSObject> output = new List<PSObject>(0);
try {
output = powerShell.AddCommand("get-" + command).AddCommand(format).AddCommand("out-string").Invoke();//pipeline.Invoke();
} catch (System.Management.Automation.RuntimeException e)
{
Console.Error.WriteLine("An Error occured while executing '" + command + "'");
Console.Error.WriteLine(e.Message);
}
//do stuff with the results
and here is the stack trace:
Unhandled Exception: System.ArgumentException: The path is not of a legal form.

at System.Management.Automation.Runspaces.RunspaceFactory.CreateRunspace()
at piramids.Program.RunCommand(Object objcommand)
at piramids.Program.Main(String[] args)
I believe this line is where the exception occurs:
System.Management.Automation.Runspaces.Runspace rs = System.Management.Automation.Runspaces.RunspaceFactory.CreateRunspace();
The CreateRunspace method is not documented to throw any exceptions, and this exception comes from so many levels down that I have no idea what kind of path this thing is checking, as I never called a function that asked for a path.
I am stumped. Does anyone have any idea what may be causing this?
EDIT: After some digging, here is what I found. PSVersionTable is a static field of VersionInfo, so the static constructor is called the first time get called for this field. The static constructor calls an internal method called GetBuildVersion, which tries to get the assembly location of PSVersionInfo. According to This documentation page:
If the assembly is loaded from a byte array, such as when using the Load(Byte[]) method overload, the value returned is an empty string ("").
I am loading from a byte array, so this will be an empty string. But then GetBuildVersion uses this location to do FileVersionInfo.GetVersionInfo which verifies the path with Path.GetFullPath. According to This documentation page:
ArgumentException:
the path is a zero-length string
So there is the problem. Now the question is, How do I assign a location to an assembly loaded from a byte array? May God have mercy on me.
I'm not at all convinced this is even remotely reasonable to expect PowerShell code to work without installing WMF. If I were approached with that request I would respond that all code must be rebuilt in another .NET language (that is, C#).
Still, perhaps you can see if it's this static method. You'll have to de-PowerShell the code I'm afraid. The PowerShell accelerator is just a simple way for me to get at the System.Management.Automation assembly. The class is not public and the method on the class is not public either.
$verInfo = [PowerShell].Assembly.GetTypes() | Where-Object Name -eq 'PSVersionInfo'
$verInfo.GetMethod('get_PSVersion', [System.Reflection.BindingFlags]'NonPublic,Static').Invoke($null, [System.Reflection.BindingFlags]'NonPublic,Static', $null, #(), $null)

Does LibGit2Sharp support cloning a repository from the local file system?

I am trying to clone a git repository from the local file system:
using System;
using LibGit2Sharp;
class Program
{
static void Main()
{
var sourceUrl = #"file:///c:/work/libgit2sharp";
using (Repository.Clone(sourceUrl, "targetDir", bare: true))
{
Console.WriteLine("repository successfully cloned");
}
}
}
and I get an exception:
Unhandled Exception: LibGit2Sharp.LibGit2SharpException: An error was raised by libgit2. Category = Odb (Error).

at Program.Main() in c:\work\ConsoleApplication1\Program.cs:line 10
I've also tried the following source url:
var sourceUrl = #"c:\work\libgit2sharp\.git\";
and got another exception:
Unhandled Exception: LibGit2Sharp.LibGit2SharpException: An error was raised by libgit2. Category = Config (Error).

targetDir is never created.
If on the other hand I use HTTP transport, the Repository.Clone method works fine:
var sourceUrl = "https://github.com/libgit2/libgit2sharp";
So my question is if I am doing something wrong or if this is unsupported feature or a bug in the native git2.dll?
So my question is if I am doing something wrong or if this is unsupported feature or a bug in the native git2.dll?
A bit a both, actually.
The first exception is clearly a bug. This should not happen and will be troubleshot.
The second one requires a deeper analysis. Would you be so kind as to open a issue in the LibGit2Sharp project?
Good news are that a pull request from BenStraub was recently merged. This pull request implements the local fetch transport which should pretty solve the issue.
LibGit2Sharp will be updated in the following days with a new a new version of libgit2 binaries which should allow you perform a local clone/fetch. I'll update this answer as soon as it's been done.
Update
This test shows how do to a Clone and a Push over against a local repository.
