Unable to cast the object type System.-.generic.keyvaluepair into system.iconvertible

 

here is my code

 

private void LoadUniversity()

{

try

{

ObjUtility = new Utility();

 

cmbUniversity.DataSource = ObjUtility.BindUniversity(StaticInfo.Center_Code).ToList();

  //////////error is after this line (May be in BindUniversity method )/////////// 

 

cmbUniversity.DisplayMember = "Value";

cmbUniversity.ValueMember = "Key";

cmbUniversity.SelectedIndex = -1;

cmbUniversity.Text = "--Select University--";

ObjUtility = null;

}

catch (Exception ex)

{

MessageBox.Show(ex.Message);

}

}

 

I am also giving here BindUniversity() method which is in Utility class ... here it is:------

 

public Dictionary<string, string> BindUniversity(string CenterCode)

{

ObjUniversityInfoModel = new UniversityInfoModel();

ObjUniversityInfoModel.CenterCode = CenterCode;

ObjUniversityInfoServiceClient = new UniversityInfoServiceClient();

ObjUniversityInfoModelRecordList = new List<UniversityInfoModel>();

ObjUniversityInfoModelRecordList = ObjUniversityInfoServiceClient.GetUniversityInfoRecordList(ObjUniversityInfoModel);

if (ObjUniversityInfoModelRecordList[0].Message == "Success" && ObjUniversityInfoModelRecordList[0].Status == true)

{

var Result = from s in ObjUniversityInfoModelRecordList

orderby s.UniversityID descending

select new

{

s.UniversityID,

s.UniversityName

};

ObjDictionary = new Dictionary<string, string>();

foreach (var Item in Result)

{

string U_ID = Item.UniversityID.ToString();

string U_Name = Item.UniversityName.ToString();

ObjDictionary.Add(U_ID, U_Name);

}

}

return ObjDictionary;

}

 

Help me....
