Public Class SecurityException
Inherits SystemException
用法
Dim instance As SecurityException
[SerializableAttribute]
[ComVisibleAttribute(true)]
public class SecurityException : SystemException
[SerializableAttribute]
[ComVisibleAttribute(true)]
public ref class SecurityException : public SystemException
/** @attribute SerializableAttribute() */
