Import json file to sql server

Question

I have 1000 records in text file. My requirement is to insert data into sql server. For that, if i can convert to xml or push to script component also fine.
Text file consists in this format...
[{"ID":1,:"Name":"test1","State":"AP"},{"ID":2,:"Name":"test2","State":"KN"}{"ID":3,:"Name":"test3","State":null}]
I'm new to coding. This is the code I wrote in scriptcomponent.
#region Class
[Micorosoft.SqlServer.Dts.Pipeline.SSISScriptComponentEntryAttribute]
public class ScriptMain: UserComponent
public override void CreateNewOutputRows()
string jsonstring = System.IO.File.ReadAllText(@"c:\t.txt");
WorkGroup[] outPutMetrics = new GetWebService(wUrl);
foreach (var metric in ouPutMetrics)
TDBuffer.AddRow();
TDBuffer.ID = metric.id;
TDBuffer.Name = metric.nm;
private WorkGroup[] GetWebService(string wUrl)
WorkGroup [] jsonResp = null;
string jsonstring = System.IO.File.ReadAllText(@"c:\t.txt");
JavaScriptSerializer sr = new JavaScriptSerializer();
jsonResp = sr.Deserialize<WorkGroup[]>(jsongstring.trim('"');
return jsonResp;
#endregion
#region JSON Class
class WorkGroup
public string id {get; set;}
public string nm {get; set;}
#endregion
I'm getting these errors when I build solution -
Expected class, delegate, enum, interface, or struct
Identifier expected
Expected class, delegate, enum, interface, or struct
Identifier expected
Type or namespace definition, or end-of-file expected
The type or namespace name WorkGroup could not be found (are you missing a using directive or an assembly reference")
GetWebServiceResult does not exist in the current context
The name wUrl does not exist in the current context
