示例

下面的代码示例创建一个动态模块、一个使用一个类型Sample T参数命名的抽象泛型类型和一个名为TestMethod的抽象方法。The following code example creates a dynamic module, an abstract generic type named Sample with one type parameter, T, and an abstract method named TestMethod. TestMethod``ByRef T采用类型ref T为的参数(在 Visual Basic 中)、指向类型的指针和的数组。 TTestMethod takes a ref parameter (ByRef in Visual Basic) of type T, a pointer to type T, and an array of T. 此方法返回的二维数组TThis method returns a two-dimensional array of T. 此代码示例将动态模块保存到磁盘,因此可以使用 MSIL 拆装器(Ildasm)对其进行检查。The code example saves the dynamic module to disk, so you can examine it using the MSIL Disassembler (Ildasm.exe).
