c#中执行批处理文件有关问题

c#中执行批处理文件问题
Process p=new Process();
try
{ p.StartInfo.FileName = lpath+"\log.bat";
  p.StartInfo.UseShellExecute = true;
  p.Start();
}
catch(Exception e)
{
  Console.writeline(e.Message);
}

上面这段代码执行后不能得到正常结果。请问怎么回事？

[解决办法]
不好意思误导你了
pro.StartInfo.WorkingDirectory = "c:\\";
运行bat文件需要设置路径


Process pro = new Process();
pro.StartInfo.UseShellExecute = true;
pro.StartInfo.FileName = @"c:\a.bat";
pro.StartInfo.CreateNoWindow = true;
pro.StartInfo.WorkingDirectory = "c:\\";
pro.Start();
