IList.IndexOf
Use the IndexOf method to determine the index of a given column mapping object.
Before calling IndexOf, you can test for the existence of a column mapping by using the Contains method.
The following example returns the index of each column in a DataColumnMappingCollection.
private void GetIndexes ( DataTableMapping myTableMap ) {
DataColumnMappingCollection myFieldsMaps = myTableMap.ColumnMappings;
// get the index of each column in the collection.
foreach ( DataColumnMapping myFieldMap in myFieldsMaps ) {
Response.Write ( myFieldsMaps.IndexOf ( myFieldMap ) );
}
}
Private Sub GetIndexes ( ByVal myTableMap As DataTableMapping )
Dim myFieldsMaps As DataColumnMappingCollection = myTableMap.ColumnMappings
Dim myFieldMap As DataColumnMapping
' get the index of each column in the collection.
For Each myFieldMap In myFieldsMaps
Response.Write ( myFieldsMaps.IndexOf ( myFieldMap ) )
Next
