Get Json Object From QueryString c# - c#

The best I found was that available solutions at stack do not have answer for nested json object, they only address liner json values. But I have data to send is like
{ ob: { a: "78", b: { a: "gffg", h: {m:67, j:"fff"} } } }
If I want to do it in php i would just do
$json = $_POST['ob'];
$obj = json_decode($json);
But In c# I can'not do that. So I would appreciate any built-in method if available and I would love to be helped to fix my following code
I want to make a nested dictionary (I would prefer JOBject though). For ease of showing output I have serialized the result,
What result I have achieved yet from following code is
{"a":"78","ob":{},"ob.b":{"a":"gffg"},"ob.b.h":{"m":"67","j":"fff"}} but desired result is like sent data { "ob": { "a": "78", "b": { "a": "gffg", "h": {m:67, "j":"fff"} } } } Code is
string getJsonStringFromQueryString()
{
Dictionary<string, object> dic = new Dictionary<string, object>();
var nvc = Request.QueryString;
foreach (string key in nvc.Keys)
{
string[] values = nvc.GetValues(key);
string tempKey = key;
tempKey = tempKey.Replace("[", ".").Replace("]", "");
if (values.Length == 1)
dic.Add(tempKey, values[0]);
else
dic.Add(tempKey, values);
}
//It is giving me
{[ob.a, 78]}
{[ob.b.a, gffg]}
{[ob.b.h.m, 67]}
{[ob.b.h.j, fff]}
var result = makeNestedObject(dic);
var json = new JavaScriptSerializer().Serialize(result);
return json;
}
I am trying to add the leaf keys and their values as it is and all other keys as dictionary
Dictionary<string, object> makeNestedObject(Dictionary<string, object> qsDictionar)
{
Dictionary<string, object> result = new Dictionary<string, object>();
foreach (string key in qsDictionar.Keys)
{
string temp = "";
if (key.Contains("."))
{
string[] ar = key.Split('.');
if (ar.Length > 2)
{
for (int i = 0; i < ar.Length - 1; i++)
{
temp = ar[0];
for (int j = 1; j <= i; j++)
{
temp += "." + ar[j];
}
//above is getting the previous key i want to use as dictionary, leaving the leaf key.
try
{
Dictionary<string, object> forTry = (Dictionary<string, object>)result[temp];
}
catch
{
result.Add(temp, new Dictionary<string, object>());
}
}
((Dictionary<string, object>)result[temp]).Add(ar[ar.Length - 1], qsDictionar[key]);
}
else
result.Add(ar[1], qsDictionar[key]);
}
}
return result;
}

Following method gives you complete solution for any json object.
string getJsonStringFromQueryString()
{
Dictionary<string, object> dic = new Dictionary<string, object>();
var nvc = Request.QueryString;
foreach (string key in nvc.Keys)
{
string[] values = nvc.GetValues(key);
string tempKey = key;
tempKey = tempKey.Replace("[", ".").Replace("]", "");
if (values.Length == 1)
dic.Add(tempKey, values[0]);
else
dic.Add(tempKey, values);
}
string vald = Request.QueryString["ob"];
var result = makeNestedObject(dic);
var json = new JavaScriptSerializer().Serialize(result);
return json;
}
Dictionary<string, object> makeNestedObject(Dictionary<string, object> qsDictionar)
{
Dictionary<string, object> result = new Dictionary<string, object>();
foreach (string key in qsDictionar.Keys)
{
if (key.Contains("."))
{
List<string> keysList = key.Split('.').ToList();
Dictionary<string, object> lastAddedDictionary = result;
while (keysList.Count > 1)
{
if (!lastAddedDictionary.ContainsKey(keysList[0]))
{
Dictionary<string, object> temp = new Dictionary<string, object>();
lastAddedDictionary[keysList[0]] = temp;
lastAddedDictionary = temp;
}
else
lastAddedDictionary = (Dictionary<string, object>)lastAddedDictionary[keysList[0]];
keysList.RemoveAt(0);
}
lastAddedDictionary[keysList[0]] = qsDictionar[key];
}
else
{
result.Add(key, qsDictionar[key]);
}
}
return result;
}

Making Hierarchical dictionary in c#

I want to build a hierarchical dictionary structure in C# from an Excel data sheet. The structure should look like this:
{
"Data": {
survey_id: {
"SurveyParameter": {},
"SurveySetting": {},
"Boreholes": {
borehole_id: {
"BoreholeParameter": {},
"BoreholeSetting": {},
"Layers": {
"Geology": {
layer_id: {"Parameter": {}, "LayerSetting": {}}
},
"Contamination": {
layer_id: {"Parameter": {}, "LayerSetting": {}}
},
},
}
},
}
}
}
"""
An example image of Excel data sheet from which the dictionary structure is to be built is provided here:
image of excel_data
I have built a dictionary structure that looks like this second image (below). But I want to convert it to the hierarchical structure, shown at the top.
image of the built dictionary
here is the text format of the dictionary saved as json file:

var reader = ExcelReaderFactory.CreateReader(stream);
var result = reader.AsDataSet();

foreach (DataTable table in tables)
{

Dictionary<(object, object), object> row;
foreach (DataRow dr in table.Rows)
{
row = new Dictionary<(object, object), object>();
foreach (DataColumn col in table.Columns)
{
object FirstcolName = table.Rows[0][col.ColumnName].ToString(); //index the first row with the column name

row.Add((FirstcolName, SecondcolName), dr[col]); //add the column names as keys and data as values in the dicttionary.using a tuple of two column headers as key
}
int index = table.Rows.IndexOf(dr); //indexing eachrow to cnvert the value in each row to string
rows.Add(index.ToString(), row); //converting to string
}
string json = JsonConvert.SerializeObject(rows, Formatting.Indented);
File.WriteAllText(#"D:\Data\test.json", json);
}
}
}
Posting the developed code for people who might need it or might be stuck in a similar problem.
This code below works for the most part as it makes the dictionary structure. However it needs to be improved with introduction of Flexible nested dictionaries that can take any types of values(including Dictionaries). This one generates the Survey_level Dictionary atleast: The nested borehole dictionary structure can only be added when we have a class that combines Boreholes Dictionary, SurveyParameter Dictionary & SurveySetting Dictionary

How to get value of a specific value of a list in C#

var ctsDB = mooe.Files66.ToList();
Dictionary<string, string> mappedfields = new Dictionary<string, string>();
Dictionary<string, string> ctsfieldsValue = new Dictionary<string, string>();
for (int i = 0; i < ctsDB.Count; i++)
{
foreach(var item in mappedfields) {
// this line returns the item.key string not the value of it.
// item.key is the column name
var rowValue = mooe.Files66.Select(k = >item.Key).ToList();
// ctsfieldsValue.Add(item.Value, rowValue);
ctsfieldsValue.ToList();
}
}
I want to iterate through ctsDB List and get the row value of a specific
column like this:
if ctsDB [i] = fileID Field612 Fiel613
and I have these column names in the value field of ctsfieldsValue.
I want to iterate on ctsDB[i] to get the value of column Field612 only.
Can anyone provide a thought?
var ctsDB = mooe.Files66.ToList();
var mappedfields = new Dictionary<string, string>(); // I assume this is not empty in your real code.
var ctsfieldsValue = new List<Dictionary<string, string>>();
foreach (var row in ctsDB)
{
var d = new Dictionary<string, string>();
foreach (var mapping in mappedfields)
{
var v = row[mapping.Key]; //throws if not found
d[mapping.Value] = v;
}
ctsfieldsValue.Add(d);
}

Compare Dictionary Key of type string to another string in C#

I'm actually trying to check if a string is equal to any of the key's in my Dictionary object.
Here is what I have done so far:
using (var oStreamReader = new StreamReader(path))
{
Dictionary<String, String> typeNames = new Dictionary<string, string>();
typeNames.Add("Kind","nvarchar(1000)");
typeNames.Add("Name","nvarchar(1000)");
DataTable oDataTable = new DataTable();
var headLine = oStreamReader.ReadLine().Trim().Replace("\"", "");
var columnNames = headLine.Split(new[] { ';' });
String[] oStreamDataValues;
/*
*create DataTable header with specific datatypes and names
*/
int countCol = 0;
foreach (string readColumn in columnNames)
{
if ((readColumn.ToString().Replace("\"", "").CompareTo(typeNames) == true))
{
// this comparison doesn't work
}
}
}
I am not quite sure what exactly you are trying to achieve. If you have a C# dictonary you can use linq to check for values that match the required value, e.g.
string valueToCompare = "Value to match";
Dictionary<string, string> dict = new Dictionary<string, string>
{
{"Key 1", "A value"},
{"Key 2", "Another value"}
};
bool found= dict.Values
.Any(value
=>
value.Equals(valueToCompare,
StringComparison.CurrentCultureIgnoreCase)
);
Since you want check if exist an entry in your Dictionary that as the same key of one of the values in your columnNames object I suggest you to use ContainsKey method
Dictionary<string, string> d = new Dictionary<string, string>();
string keyvalue;
if (d.ContainsKey("value to find"))
{
if (d.TryGetValue("value to find", out keyvalue))
{

I have solved this (by inspiration of Paul Houlston and Thomas Lielacher)
string headLine = oStreamReader.ReadLine().Trim().Replace("\"", "");
string columnNames = headLine.Split(new[] { ';' });
foreach (string readColumn in columnNames)
{
if (typeNames.Keys.Contains(readColumn, StringComparer.CurrentCultureIgnoreCase) == true)
{
DataColumn oDataColumn = new DataColumn(readColumn,typeof(System.String));
oDataTable.Columns.Add(oDataColumn);
}
}

resxResourceReader only read when xml:space is present

I am surely missing something small here. I am trying to open multiple resx files, load them into a dictionary, then cross reference a translation file. The problem is that when I open up the resx file with resxResourceReader, it reads in all the the form setup data as well. I.E. container information, control names, etc.
Now I noticed in the resx file that the entries I want have "xml:space" along with them. What is the correct way to only get the strings I want, and leave all the other stuff behind?
Thanks!
foreach (String s in sourceLocations)
{
Dictionary<string, string> sourceTemp = new Dictionary<string, string>();
Dictionary<string, object> Temp = new Dictionary<string, object>();
using (ResXResourceReader rsxr = new ResXResourceReader(s))
{
foreach (DictionaryEntry entry in rsxr)
{
string[] parts = s.Split('\\');
if (!entry.Key.ToString().Contains(">>"))
{
sourceTemp.Add(parts[parts.Count() - 1] + "_" + entry.Key.ToString(), entry.Value.ToString());
}
}
sources.Add(sourceTemp);
}
}
For anyone who runs into this later, this ended up working :
foreach (String s in sourceLocations)
{
Dictionary<string, string> sourceTemp = new Dictionary<string, string>();
Dictionary<string, object> Temp = new Dictionary<string, object>();
using (ResXResourceReader rsxr = new ResXResourceReader(s))
{
rsxr.UseResXDataNodes = true;
foreach (DictionaryEntry entry in rsxr)
{
string[] parts = s.Split('\\');
if ((!entry.Key.ToString().Contains(">>")))
{
if (isNodeString((ResXDataNode)entry.Value))
sourceTemp.Add(parts[parts.Count() - 1] + "_" + entry.Key.ToString(), getNodeValue((ResXDataNode)entry.Value));
}
}
sources.Add(sourceTemp);
}
}
private string getNodeValue(ResXDataNode node)
{
if (node.FileRef == null)
{
return node.GetValue((ITypeResolutionService)null).ToString();
}
else return String.Empty;
}
private bool isNodeString(ResXDataNode node)
{
string result = node.GetValueTypeName((ITypeResolutionService)null);
if (result.Contains("System.String")) return true;
else return false;
}

Add to dictionary some params from request

I want to get some params from Request
I need from Request.Params all params with text contains "txt" I have more type of text structure:
"ctl00$cphMain$repDelTypes$ctl00$ucDel$txtPhone"
"ctl00$cphMain$repDelTypes$ctl00$ucDel$txtPhone2"
"ctl00$cphMain$repDelTypes$ctl00$ucDel$txtPhone3"
"ctl00$cphMain$repDelTypes$ctl00$ucDel$txtAdr1"
"ctl00$cphMain$repDelTypes$ctl00$ucDel$txtAdr2"
"ctl00$cphMain$repDelTypes$ctl00$ucDel$txtAdr3"
how Get value all text after "txt"
var dictionary = new Dictionary<string, string>();
foreach (var key in Request.Params.AllKeys)
{
if (key.ToString().Contains("txt"))
{
// add to dictionary name and value
// dictionary.Add("name", "val");
}
}
You can do this:
var dictionary = new Dictionary<string, string>();
foreach (var key in Request.Params.AllKeys)
{
if (key.ToString().Contains("txt"))
{
int index = Request.Params[key].LastIndexOf("txt");
Dictionary.Add(key, Request.Params[key].SubString(index));
}
}
Are you asking how to add to the dictionary?
var dictionary = new Dictionary<string, string>();
foreach (var key in Request.Params.AllKeys)
{
if (key.ToString().Contains("txt"))
{
//get the text after "txt"
var index = Request.Params[key].LastIndexOf("txt");
var val = Request.Params[key].SubString(index);
Dictionary.Add(key, val);
}
}
var dictionary = new Dictionary<string, string>();
foreach (var key in Request.Params.AllKeys)
{
if (key.ToString().Contains("txt"))
{
// add to dictionary name and value
dictionary.Add(key.Split(new string[]{"txt"}, StringSplitOptions.None)[1], Request.Params[key]);
}
}
