An SqlTransaction should be used for a particular SqlConnection. In your case, the SqlTransaction belongs to another SqlConnection, and hence, it is throwing such Exception message.

You need to obtain the SqlTransaction from the SqlConnection obejct, by using the following piece of code:

sqlTransaction = sqlConnection.BeginTransaction();

I've provided you a sample code which you could follow:

public MyMethod()
{
	SqlConnection sqlConnection = null;
        SqlTransaction sqlTransaction = null;
        try
        {
            //Get Connection object
            sqlConnection = GetDataConnection();
            //Obtain SqlTransaction object from Connection object
            sqlTransaction = sqlConnection.BeginTransaction(); 

            MyMethod1(Input, sqlConnection, sqlTransaction)
            MyMethod2(Input, sqlConnection, sqlTransaction)

            sqlTransaction.Commit();
        }
        catch(Exception e)
        {
            if (sqlTransaction!=null) {sqlTransaction.Rollback()};
            throw new Exception("Failure in method x", e) ;
        }
        finally
        {
            if(sqlConnection!=null && sqlConnection.State==ConnectionState.Open)
            {
                sqlConnection.Close();
            }
        } 
}

Hope this helps
