Parameters

  • ordinal
    The zero-based column ordinal.

Return Value

The value of the specified column.

Exceptions

Exception type Condition

InvalidCastException

The specified cast is not valid.

SqlNullValueException

The value is a 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 Edition 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.
