c# 执行dos命令问题

[wangs_1]

大家帮我看看问题出在哪里，执行完后，一点效果也没有。（应该弹出dos出口才对）
string fileName = Path.Combine(Path.GetDirectoryName(this.GetType().Assembly.Location), "moveuser.exe");
ProcessStartInfo expressStartInfo = new ProcessStartInfo();
expressStartInfo.FileName =fileName;
expressStartInfo.Arguments = txtSource.Text.Trim() + " " + txtPurPose.Text.Trim() + " " + "/y/k";
expressStartInfo.CreateNoWindow = true;
expressStartInfo.RedirectStandardError = true;
expressStartInfo.RedirectStandardInput = true;
expressStartInfo.RedirectStandardOutput = true;
expressStartInfo.UseShellExecute = false;
using (Process expressProc = new Process())
{
expressProc.StartInfo = expressStartInfo;
expressProc.StartInfo.WindowStyle = ProcessWindowStyle.Normal;
expressProc.Start();
//expressProc.WaitForExit();


}

检查下路径是否有空格

调用命令行参数?
