ULParameter class

Represents a parameter to a ULCommand. This class cannot be inherited.

Syntax

Visual Basic
Public NotInheritable Class ULParameter
  Inherits DbParameter
  Implements ICloneable

C#
public sealed class ULParameter: DbParameter,
  ICloneable

Remarks

A ULParameter object can be created directly using one of its many constructors, or using the ULCommand.CreateParameter method. Because of the special treatment of the 0 and 0.0 constants and the way overloaded methods are resolved, it is highly recommended that you explicitly cast constant values to type object when using the ULParameter(string,object) constructor. For example:

' Visual Basic
Dim p As ULParameter = New ULParameter( "", CType( 0, Object ) )

// C#
ULParameter p = new ULParameter( "", (object)0 );

Parameters (including those created by ULCommand.CreateParameter) must be added to a ULCommand.Parameters collection to be used. All parameters are treated as positional parameters and are used by a command in the order that they were added.

In UltraLite.NET, parameters can only be used as IN parameters and all mapping information is ignored. Only the ULParameter.Value is important.
