DataTableReader.GetProviderSpecificFieldType Method

Gets the type of the specified column in provider-specific format.

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

public override Type GetProviderSpecificFieldType(
	int ordinal
)

Parameters

ordinal
Type: System.Int32
The zero-based column ordinal.

Return Value

Type: System.Type
The Type that is the data type of the object.

ExceptionCondition
ArgumentOutOfRangeException

The index passed was outside the range of 0 to FieldCount - 1.

InvalidOperationException

An attempt was made to read or access a column in a closed DataTableReader.

Because the DataTableReader always returns the type stored within the underlying DataColumn, the value returned by calling the GetProviderSpecificFieldType method always returns the same type as the type stored within the DataTable. When you work with the DataTableReader class, calling the GetProviderSpecificFieldType method returns the same type as calling the GetType method.
