Lets you efficiently bulk load a SQL Server table with data from another source.
Assembly: System.Data (in System.Data.dll)
Microsoft SQL Server includes a popular command-prompt utility named bcp for moving data from one table to another, whether on a single server or between servers. The class lets you write managed code solutions that provide similar functionality. There are other ways to load data into a SQL Server table (INSERT statements, for example), but offers a significant performance advantage over them.
The class can be used to write data only to SQL Server tables. However, the data source is not limited to SQL Server; any data source can be used, as long as the data can be loaded to a DataTable instance or read with a IDataReader instance.
The following console application demonstrates how to load data using the class. In this example, a SqlDataReader is used to copy data from the Production.Product table in the SQL Server 2005 AdventureWorks database to a similar table in the same database.
This sample will not run unless you have created the work tables as described in Bulk Copy Example Setup (ADO.NET). This code is provided to demonstrate the syntax for using SqlBulkCopy only. If the source and destination tables are in the same SQL Server instance, it is easier and faster to use a Transact-SQL INSERT … SELECT statement to copy the data.
