DataColumnCollection.IndexOf Method (DataColumn)

Gets the index of a column specified by name.

Namespace: System.Data
Assembly: System.Data (in system.data.dll)

public int IndexOf (
	DataColumn column
)
public int IndexOf (
	DataColumn column
)
public function IndexOf (
	column : DataColumn
) : int

Parameters

column

The name of the column to return.

Return Value

The index of the column specified by column if it is found; otherwise, -1.

The IndexOf method is not case-sensitive.

The following example uses the Contains method to determine whether a specified column exists in a DataColumnCollection. If so, the IndexOf method returns the index of the column.

private void GetIndex(DataTable table)
{
    DataColumnCollection columns = table.Columns;
    if(columns.Contains("City")) 
    {
        Console.WriteLine(columns.IndexOf("City"));
