INullable

System.Data.SqlTypes (system.data.dll) interface

.NET system types can't contain the value null . However, database values can because this value can; a null value indicates the absence of a value. All SQLType s implement the INullable interface to enable them to contain the null value.

 public interface  INullable  {  // Public Instance Properties  public bool  IsNull  {get; }  }
