我有一个用C＃编写的Windows服务，它只是在文件被放入监视文件夹时尝试执行VB脚本。虽然如果我只是双击它，脚本将启动正常，但它似乎不是由服务启动的。您将在下面的代码中看到我正在写入一个日志，似乎它认为它正在尝试启动cscript并执行脚本但奇怪的是在30秒之后它只是以退出代码0终止。
public static void ExecVB_Script(string scriptpath)
{
try
{
WriteErrorLog("Execute VB instruction received. Attempting to run VB script " + scriptpath);
if (!File.Exists(scriptpath))
{
WriteErrorLog("Error: VB script execution Failed. Cannot find script " + scriptpath);
}
else
{
WriteErrorLog("Starting cscript.exe");
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.FileName = @"cscript.exe";
startInfo.WorkingDirectory = ConfigurationManager.AppSettings["VBScriptExecPath"];
WriteErrorLog("Working Directory is: " + startInfo.WorkingDirectory.ToString());
startInfo.Arguments = string.Format(@" //B //Nologo " + scriptpath);
WriteErrorLog("Arguements passed: "+ startInfo.Arguments);
startInfo.RedirectStandardOutput = true;
startInfo.RedirectStandardError = true;
startInfo.UseShellExecute = false;
startInfo.CreateNoWindow = true;
System.Diagnostics.Process process = new System.Diagnostics.Process();
process.StartInfo = startInfo;
WriteErrorLog("Attempting to execute VB script");
process.Start();
process.WaitForExit();
WriteErrorLog("cscript.exe has finished");
WriteErrorLog(process.ExitCode.ToString());
}
}
日志文件输出。

该服务作为本地管理员运行，我也以本地管理员身份登录，因此似乎不太可能是访问或权限问题。此外，当手动执行VB脚本时，它还会写入文本日志，但是当C #Windows服务触发时，没有写入日志，这表明VB脚本根本没有被执行。
