[DllImport("shell32.dll", EntryPoint="ShellExecute")] public static extern int ShellExecute ( int hwnd, string lpOperation, string lpFile, string lpParameters, string lpDirectory, int nShowCmd );
提示如下错误: D:\Vs2003Progrm\WinApp2\Form1.cs(22): 找不到类型或命名空间名称“DllImport”(是否缺少 using 指令或程序集引用?) 该怎么办呀?
using System.Runtime.InteropServices; 或者 [System.Runtime.InteropServices.DllImport("shell32.dll", EntryPoint="ShellExecute")]
