DataTableReader.GetProviderSpecificValue(Int32) Method

Definition

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

public:
 override System::Object ^ GetProviderSpecificValue(int ordinal);
public override object GetProviderSpecificValue (int ordinal);
override this.GetProviderSpecificValue : int -> obj
Public Overrides Function GetProviderSpecificValue (ordinal As Integer) As Object

Parameters

ordinal
Int32

The zero-based number of the column whose value is retrieved.

Returns

The value of the specified column in provider-specific format.

Exceptions

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

An attempt was made to retrieve data from a deleted row.

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

Remarks

Because the DataTableReader always returns the type stored within the underlying DataColumn, the value returned by calling the GetProviderSpecificValue method always returns data of the same type as the data stored within the DataTable. When you work with the DataTableReader class, calling the GetProviderSpecificValue method returns the same value and type as calling the GetValue method.
