C# How to add Jarray to List<Dictionary<string, dynamic>>

Question

I am new to C# .net . I am trying to add my Jarray to a dictionary Dictionary<string, dynamic> and then to a list List<Dictionary<string, dynamic>> .

My string is something like :

Response = "[{\"name\":\"ABCD\",\"caption\":\"ABCDCaption\",\"description\":\"ABCDDesc\"},{\"name\":\"ABCD\",\"caption\":\"ABCDCaption\",\"description\":\"ABCDCaption\"},{\"name\":\"XYZ.exe\",\"caption\":\"XYZCaption\","description":\"XYZdesc\"}]"

The code is :

JArray a = JArray.Parse(Response);

foreach (JObject o in bb.Children<JObject>())
{
foreach (JProperty p in o.Properties())
{
  string name = p.Name;
  var value = p.Value;
  DicSQLData.Add(key: name, value: value);                      

}
ListSQLData.Add(DicSQLData);

}

It works fine for first set of data

{\"name\":\"ABCD\",\"caption\":\"ABCDCaption\",\"description\":\"ABCDDesc\"}

For second set it gives error as dictionary does not add duplicate key. How to fix this? Any help is really appreciated.

I think we're missing some of the code, but you're seeing that error because you're not initializing a new dictionary on each loop iteration, you're inserting into the same dictionary causing the key errors.

Try doing this instead. Notice each iteration makes a new dictionary and then inserts it into the list

JArray a = JArray.Parse(Response);

foreach (JObject o in bb.Children<JObject>())
{
    //make new dictionary
    var DicSQLData = new Dictionary<string, dynamic>();

    foreach (JProperty p in o.Properties())
    {     
      string name = p.Name;
      var value = p.Value;
      DicSQLData.Add(key: name, value: value);                      
    }

    //add dictionary to list
    ListSQLData.Add(DicSQLData);
}
