OdbcDataReader::GetOrdinal Method (String^)

 

Gets the column ordinal, given the name of the column.

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

public:
virtual int GetOrdinal(
	String^ value
) override

Parameters

value
Type: System::String^

The name of the column.

Return Value

Type: System::Int32

The zero-based column ordinal.

GetOrdinal performs a case-sensitive lookup first. If it fails, a second case-insensitive search is made. The method throws an IndexOutOfRange exception if the zero-based column ordinal is not found.

GetOrdinal is kana-width insensitive.

Because ordinal-based lookups are more efficient than named lookups, it is inefficient to call GetOrdinal within a loop. Instead, call GetOrdinal one time and then assign the results to an integer variable for use within the loop.

The following example demonstrates how to use the GetOrdinal method.
