Gets or sets the name of the source column mapped to the DataSet and used for loading or returning the Value

Namespace:   System.Data.SqlClient
Assembly:  System.Data (in System.Data.dll)

public override string SourceColumn { get; set; }

Property Value

Type: System.String

The name of the source column mapped to the DataSet. The default is an empty string.

When SourceColumn is set to anything other than an empty string, the value of the parameter is retrieved from the column with the SourceColumn name. If Direction is set to Input, the value is taken from the DataSet. If Direction is set to Output, the value is taken from the data source. A Direction of InputOutput is a combination of both.

For more information about how to use the SourceColumn property, see DataAdapter Parameters and Updating Data Sources with DataAdapters.

The following example creates a SqlParameter and sets some of its properties.

static void CreateSqlParameterSourceColumn()
{
    SqlParameter parameter = new SqlParameter("Description", SqlDbType.VarChar, 88);
    parameter.SourceColumn = "Description";
}
