| Exception | Condition |
|---|---|
| ArgumentException | The column specified by column cannot be found. |
| ArgumentNullException | The column is null. |
| DeletedRowInaccessibleException | Occurs when attempting to set a value on a deleted row. |
| InvalidCastException | The value type of the underlying column could not be cast to the type specified by the generic parameter, T. |
If value is null, the SetField<'T> method converts the null value to Value in the underlying DataColumn.
The SetField<'T> method does not perform any type conversions. This does not mean, however, that a type conversion will not occur. The SetField<'T> method exposes the ADO.NET 2.0 behavior of the DataRow class. A type conversion could be performed by the DataRow object and the converted value would then be saved to the row.
Exceptions can be passed up through the SetField<'T> method from the underlying DataRow object.
