SqlBulkCopy Not Working

Question

I have a DataSet populated from Excel Sheet. I wanted to use SQLBulk Copy to Insert Records in Lead_Hdr table where LeadId is PK.

Answer 1

One of the reason is that :SqlBukCOpy is case sensitive . Follow steps:

1. In that Case first you have to find your column in Source Table by using "Contain" method in C#.
2. Once your Destination column matched with source column get index of that column and give its column name in SqlBukCOpy .

For Example:`

//Get Column from Source table 
  string sourceTableQuery = "Select top 1 * from sourceTable";
   DataTable dtSource=SQLHelper.SqlHelper.ExecuteDataset(transaction, CommandType.Text, sourceTableQuery).Tables[0];// i use sql helper for executing query you can use corde sw

 for (int i = 0; i < destinationTable.Columns.Count; i++)
                        {    //check if destination Column Exists in Source table
                            if (dtSource.Columns.Contains(destinationTable.Columns[i].ToString()))//contain method is not case sensitive
                            {
                                int sourceColumnIndex = dtSource.Columns.IndexOf(destinationTable.Columns[i].ToString());//Once column matched get its index
                                bulkCopy.ColumnMappings.Add(dtSource.Columns[sourceColumnIndex].ToString(), dtSource.Columns[sourceColumnIndex].ToString());//give coluns name of source table rather then destination table so that it would avoid case sensitivity
                            }

                        }
                        bulkCopy.WriteToServer(destinationTable);
                        bulkCopy.Close();
