Recently i worked with making some ajax calls to the server. There we need to get the response from the server as a JSON string. I have used two ways of returning a JSON string from a ASP.NET WebMethod.
Method 1 - Uses the JavaScriptSerializer
[WebMethod]
public string GetLankanList()
{
JavaScriptSerializer serializer = new JavaScriptSerializer();
List lankanList = new List();
string[] names = { "chamara", "janaka", "asanka" };
for (int i = 0; i < names.Length; i++)
{
Lankans srilankans = new Lankans();
srilankans.Name = names[i];
lankanList.Add(srilankans);
}
string jsonString = serializer.Serialize(lankanList);
return jsonString;
}
Method 2 - Uses ScriptMethod with the WebMethod
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string getData()
{
try
{
string name="chamara";
return name;
}
catch (Exception ex) {
throw ex;
}
}
