Source:

DataTableMapping.cs

Initializes a new instance of the DataTableMapping class when given a source table name, a DataTable name, and an array of DataColumnMapping objects.

public DataTableMapping(string? sourceTable, string? dataSetTable, System.Data.Common.DataColumnMapping[]? columnMappings);

Parameters

sourceTable

String

The case-sensitive source table name from a data source.

dataSetTable

C#

public void CreateDataTableMapping()
{
    // ...
    // create mappings
    // ...

    DataColumnMapping[] columns1 = {};
    mappings.CopyTo(columns1, 0);
    DataTableMapping mapping =
        new DataTableMapping("Categories", "DataCategories", columns1);

    DataColumnMapping[] columns2 = {};
    mapping.ColumnMappings.CopyTo(columns2, 0);
}
