DataRowExtensions::SetField<T> Method (DataRow^, Int32, T)
Sets a new value for the specified column in the DataRow the method is called on. The SetField<T> method also supports nullable types.
Assembly: System.Data.DataSetExtensions (in System.Data.DataSetExtensions.dll)
public: generic<typename T> [ExtensionAttribute] static void SetField( DataRow^ row, int columnIndex, T value )
Parameters
- row
-
Type:
System.Data::DataRow^
The input DataRow, which acts as the this instance for the extension method.

-
Type:
System::Int32
The zero-based ordinal of the column to set the value of.

The new row value for the specified column, of type T.
Type Parameters
- T
A generic parameter that specifies the value type of the column.
| Exception | Condition |
|---|---|
| DeletedRowInaccessibleException | Occurs when attempting to set a value on a deleted row. |
| IndexOutOfRangeException | The ordinal argument is out of range. |
| InvalidCastException | The value type of the underlying column could be not 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.
