Read StandardOutput Process from BackgroundWorkerProcess method
- by Nicola Celiento
Hi all,
I'm working with a BackgroundWorker Process from Windows .NET C# application.
From the async method I call many instance of cmd.exe Process (foreach), and read from StandardOutput, but at the 3-times cycle the ReadToEnd() method throw Timeout Exception.
Here the code:
StreamWriter sw = null;
DataTable dt2 = null;
StringBuilder result = null;
Process p = null;
for(DataRow dr in dt1.Rows)
{
arrLine = new string[4]; //new row
result = new StringBuilder();
arrLine[0] = dr["ID"].ToString();
arrLine[1] = dr["ChangeSet"].ToString();
#region Initialize Process CMD
p = new Process();
ProcessStartInfo info = new ProcessStartInfo();
info.FileName = "cmd.exe";
info.CreateNoWindow = true;
info.RedirectStandardInput = true;
info.RedirectStandardOutput = true;
info.RedirectStandardError = true;
info.UseShellExecute = false;
p.StartInfo = info;
p.Start();
sw = new StreamWriter(p.StandardInput.BaseStream);
#endregion
using (sw)
{
if (sw.BaseStream.CanWrite)
{
sw.WriteLine("cd " + this.path_WORKDIR);
sw.WriteLine("tfpt getcs /changeset:" + arrLine[1]);
}
}
string strError = p.StandardError.ReadToEnd(); // Read shell error output commmand (TIMEOUT)
result.Append(p.StandardOutput.ReadToEnd()); // Read shell output commmand
sw.Close();
sw.Dispose();
p.Close();
p.Dispose();
}
Timeout is on code line:
string strError = p.StandardError.ReadToEnd();
Can you help me?
Thanks!
