How to insert bulk copy data in to SQL using SqlBulkCopy in .NET?

When we need to insert a bulk copy of data in to SQL.we have to follow the SqlBulkCopy class to make this process to be simple.

Let us illustrate with an example. Suppose we have excel file or csv file now we need to insert all the data to SQL.

In such cases we must follow the below method.

Initially we need to get all the data from the excel file or CSV file. In a previous article I have written about to import the data from excel file and CSV file.

Once you imported all the data into DATATABLE. Now you have all the data in databale, instead of using loop method you have to use SqlBulkCopy class.

using (SqlBulkCopy copy = new SqlBulkCopy(cn))                 {                     copy.ColumnMappings.Add(0, 0);                     copy.ColumnMappings.Add(1, 1);                     copy.ColumnMappings.Add(2, 2);                     copy.ColumnMappings.Add(3, 3);                     copy.ColumnMappings.Add(4, 4);                     copy.DestinationTableName = "product";                     copy.WriteToServer(dt);                 }

That’s it …….
