DataRowExtensions.SetField Method (System.Data) | Microsoft Learn

Sets a new value for the specified column in the DataRow.

Sets a new value for the specified column in the DataRow. The SetField<T>(DataRow, DataColumn, T) method also supports nullable types.

Sets a new value for the specified column in the DataRow the method is called on. The SetField<T>(DataRow, Int32, T) method also supports nullable types.

Sets a new value for the specified column in the DataRow. The SetField<T>(DataRow, String, T) method also supports nullable types.

public static void SetField<T>(this System.Data.DataRow row, System.Data.DataColumn column, T? value);

static member SetField : System.Data.DataRow * System.Data.DataColumn * 'T -> unit

<Extension()>
Public Sub SetField(Of T) (row As DataRow, column As DataColumn, value As T)

T

A generic parameter that specifies the value type of the column.

row

DataRow

The input DataRow, which acts as the this instance for the extension method.

value

T

The new row value for the specified column, of type T.

The column specified by column cannot be found.

Occurs when attempting to set a value on a deleted row.

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 method converts the null value to DBNull.Value in the underlying DataColumn.

The SetField method does not perform any type conversions. This does not mean, however, that a type conversion will not occur. The SetField 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 method from the underlying DataRow object.

The new row value for the specified column, of type T.

Occurs when attempting to set a value on a deleted row.

The columnIndex argument is out of range.
