IDataRecord.GetFieldType Method

Gets the Type information corresponding to the type of Object that would be returned from GetValue.

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

Type GetFieldType(
	int i
)

Parameters

i
Type: System.Int32

The index of the field to find.

Return Value

Type: System.Type
The Type information corresponding to the type of Object that would be returned from GetValue.

ExceptionCondition
IndexOutOfRangeException

The index passed was outside the range of 0 through FieldCount.

This information can be used to increase performance by indicating the strongly-typed accessor to call. (for example, using GetInt32 is roughly ten times faster than using GetValue.)
