How to download JSON string from url using web client and convert JSON to datatable in Asp.net(C#).

Here I will explain how to download JSON string from page url and how to set User-Agent in header.
Also Convert JSON string into Datatable.

string str = "type your json url here";

WebClient webClient = new WebClient();
if (webClient == null)
{
    webClient = new WebClient();
}
else
{
    webClient.Dispose();
    webClient = null;
    webClient = new WebClient();
}

DataTable JsonDataTable = new DataTable(); 

//Set Header
webClient.Headers["User-Agent"] = "Mozilla/4.0 (Compatible; Windows NT 5.1; MSIE 6.0) (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)";

//Download Content
string JsonSting = webClient.DownloadString(str);

//Convert JSON to Datatable
JsonDataTable = (DataTable)JsonConvert.DeserializeObject(JsonSting, (typeof(DataTable)));
JsonDataTable.TableName = "JSON_MAST";
