  • C# ShellExcute与Process

    C#运行外部程序的两种方法

    ShellExecute

    using System.Runtime.InteropServices;
    
    public enum ShowWindowCommands : int
    {
    
        SW_HIDE = 0,
        SW_SHOWNORMAL = 1,    //用最近的大小和位置显示,激活
        SW_NORMAL = 1,
        SW_SHOWMINIMIZED = 2,
        SW_SHOWMAXIMIZED = 3,
        SW_MAXIMIZE = 3,
        SW_SHOWNOACTIVATE = 4,
        SW_SHOW = 5,
        SW_MINIMIZE = 6,
        SW_SHOWMINNOACTIVE = 7,
        SW_SHOWNA = 8,
        SW_RESTORE = 9,
        SW_SHOWDEFAULT = 10,
        SW_MAX = 10
    }
    [DllImport("shell32.dll")]
    public static extern IntPtr ShellExecute(
        IntPtr hwnd,
        string lpszOp,
        string lpszFile,
        string lpszParams,
        string lpszDir,
        ShowWindowCommands FsShowCmd
    );
    

    调用

    ShellExecute(IntPtr.Zero, "open", UrlOrPath, null, null, ShowWindowCommands.SW_SHOWNORMAL);
    

    UrlOrPath可为exe路径或者网页url(使用默认浏览器打开网页url)

    使用ie打开网页url

    ShellExecute(NULL, "open", "IEXPLORE", "http://www.csdn.net", NULL, SW_SHOWMAXIMIZED);
    

    Process

    using System.Diagnostics;
    
    private static string Execute(string exePath, string parameters)
    {
        string result = String.Empty;
    
        using (Process p = new Process())
        {
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.CreateNoWindow = true;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.FileName = exePath;
            p.StartInfo.Arguments = parameters;
            p.Start();
            p.WaitForExit();
    
            result = p.StandardOutput.ReadToEnd();
        }
    
        return result;
    }
