) As Decimal
'Usage

public override decimal GetDecimal(
    int ordinal
)

public:
virtual Decimal GetDecimal(
    int ordinal
) override

abstract GetDecimal : 
        ordinal:int -> decimal 
override GetDecimal : 
        ordinal:int -> decimal

public override function GetDecimal(
    ordinal : int
) : decimal

Parameters

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

Return Value

Type: System.Decimal
The value of the specified column.

Implements

IDataRecord.GetDecimal(Int32)

Exceptions

Exception	Condition
InvalidCastException	The specified cast is not valid.
SqlNullValueException	The value is nulla null reference (Nothing in Visual Basic).
InvalidOperationException	The operation is not valid. The SqlCeDataReader may be positioned after the last row in the result set.

Remarks

No conversions are performed; therefore, the data retrieved must already be a Decimal object.

The maximum size of the SQL Server Compact decimal is greater than the maximum size of Decimal. For example, an overflow can occur when SqlCeDataReader is reading values that are either greater than Decimal.MaxValue or lesser than Decimal.MinValue.

Call IsDBNull to check for null values before calling this method.
