process的StandardInput属性怎么用

using System; using System.Diagnostics; using System.IO; public class StandardInputTest { public static void Main() { Process p2=new Process(); p2.StartInfo.FileName="test1.exe"; p2.StartInfo.UseShellExecute=false; p2.StartInfo.RedirectStandardInput=true; p2.StartInfo.RedirectStandardOutput=true; p2.Start(); StreamWriter input = p2.StandardInput; input.WriteLine("How Are You."); input.Close(); StreamReader output = p2.StandardOutput; Console.WriteLine(output.ReadToEnd()); } } //付：test1.cs //请编译 csc /out:test1.exe test1.cs using System; class testcs { public static void Main () { String str = Console.ReadLine(); Console.WriteLine(str); } }

SendMessage 发送按钮点击事件 按钮没响应，该怎么解决

c#程序给另一个C#程序发送按钮点击事件的时候按钮是有相应的。

可是给其他的一个第三方程序发送按钮点击事件的时候，按钮就没有相应了。

按钮的句柄这些都用spy++查看了，没有问题，有谁知道这可能是什么方面的原因吗？ string aDir = @"D:gcTonsinsoftMultiTaxMtdeclare.exe"; ProcessStartInfo aStartInfo = new ProcessStartInfo(); aStartInfo.CreateNoWindow = true; aStartInfo.FileName = aDir; aStartInfo.UseShellExecute = true; aStartInfo.WorkingDirectory = @"D:gcTonsinsoftMultiTax"; System.Diagnostics.Process.Start(aStartInfo); Thread.Sleep(1000); ParenthWnd = FindWindow("TLoginDialog", null); ////用户名 ParenthWnd_sub = FindWindowEx(ParenthWnd, EdithWnd, "TRzEdit", ""); SendMessage(ParenthWnd_sub, WM_SETTEXT, (IntPtr)0, this.txtName.Text.Trim()); ////密码 ParenthWnd_sub = FindWindowEx(ParenthWnd, ParenthWnd_sub, "TRzEdit", ""); SendMessage(ParenthWnd_sub, WM_SETTEXT, (IntPtr)0, this.txtPsw.Text.Trim()); //确定按钮 ParenthWnd_sub = FindWindowEx(ParenthWnd, (IntPtr)0, "TRzBitBtn", "登录(&O)"); SendMessage(ParenthWnd_sub, WM_CLICK, 0, 0);

怎么在C#中执行DOS命令

public static string RunCmd(mand)//运行一个cmd命令 { Process p = new Process(); p.StartInfo.WorkingDirectory = "c:\"; p.StartInfo.FileName = "cmd.exe"; //程序名 p.StartInfo.Arguments = "/c " +mand; p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardInput = true; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.RedirectStandardError = true; //重定向错误输出 p.StartInfo.CreateNoWindow = true; //不显示窗口 p.Start(); return p.StandardOutput.ReadToEnd(); }
