Public Shared Function GetFunctionPointerForDelegate (d As Delegate) As IntPtr

参数

d: Delegate

要传递给非托管代码的委托。

IntPtr

nativeint

一个可传递给非托管代码的值，非托管代码使用该值来调用基础托管委托。

属性: ObsoleteAttribute SecurityCriticalAttribute

例外

ArgumentException

d 参数是泛型类型定义。

ArgumentNullException

d 参数为 null。

注解

d委托将转换为可以使用默认平台调用约定传递给非托管代码的函数指针。可以通过将应用于 UnmanagedFunctionPointerAttribute 委托来设置调用约定。

必须手动防止垃圾回收器从托管代码中收集委托。垃圾回收器不跟踪对非托管代码的引用。
