public:
property bool CanBeNull {
	bool get();
	void set(bool value);
}

Property Value

Type: System::Boolean

Default = true.

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

System_CAPS_noteNote

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.
