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

委托 d 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。
