Solution 1

The problem is you have declared the parameter as varchar in procedure, but passing it as a integer value.

C#

{"@contactid",Convert.ToInt32(Txtcontactid.Text)}};
        DBTask.ExecuteQuery_SP("sp_DeleteContactSubscriptionDetail", objdel);

If you are converting here, then declare the parameter as integer in procedure.

You are unnecessarily converting again in procedure using...

SQL

set @contactid=convert (int, @contactid)

So, declare as integer and try.

SQL

@contactid as int
