Gets or sets whether a column can contain null values.

Namespace: System.Data.Linq.Mapping
Assembly: System.Data.Linq (in System.Data.Linq.dll)

Syntax

'Declaration
Public Property CanBeNull As Boolean

public bool CanBeNull { get; set; }

Type: System.Boolean
Default = true.

If you set this value to false, the data in the corresponding column is assumed to be non-null.

Note:
This property is duplicated from the DbType property for convenience. The CreateDatabase method uses only the DbType property. For this reason, you must specify whether a column can contain null values in the DbType property also.
