IMethodReturnMessage.OutArgs 属性

  • 项目

返回标记为 ref 或 out 参数的指定参数。

**命名空间:**System.Runtime.Remoting.Messaging
**程序集:**mscorlib（在 mscorlib.dll 中）

语法

声明
ReadOnly Property OutArgs As Object()
用法
Dim instance As IMethodReturnMessage
Dim value As Object()

value = instance.OutArgs

Object[] OutArgs { get; }

property array<Object^>^ OutArgs {
    array<Object^>^ get ();
}

/** @property */
Object[] get_OutArgs ()

function get OutArgs () : Object[]

属性值

标记为 ref 或 out 参数的指定参数。

异常

异常类型 条件

SecurityException

直接调用方通过接口引用进行调用，它没有基础结构权限。

备注

虽然 OutArgs 属性是多余的（因为可以通过 OutArgCount 字段和 GetOutArg 方法达到相同的功能），但如果实施者理解何时检索所有参数，则可能获得性能优化。
