	string tableName
)

	tableName : String

Not applicable.

Parameters

tableName

The name of the DataTable object to look for.

Return Value

The zero-based index of the DataTable with the specified name, or -1 if the table does not exist in the collection.
NoteNote:

Returns -1 when two or more tables have the same name but different namespaces. The call does not succeed if there is any ambiguity when matching a table name to exactly one table.

You specify the name of the DataTable object by using the TableName property.

The following example returns the index of a named table in the DataTableCollection.

private void GetIndexes()
{
    // Get the DataSet of a DataGrid.
    DataSet thisDataSet = (DataSet)DataGrid1.DataSource;

    // Get the DataTableCollection through the Tables property.
    DataTableCollection tables = thisDataSet.Tables;

    // Get the index of the table named "Authors", if it exists.
    if (tables.Contains("Authors"))
        System.Diagnostics.Debug.WriteLine(tables.IndexOf("Authors"));
}
