这几天做一个通讯程序，要通过“运行”开启一个进程
结果有时候可以正常调用，有时候就出现问题
出问题代码如下：

Process p=Process.Start(t_path.Text.ToString(),t_file.Text.ToString());
Process.start()第一个参数是运行的程序名称，后面是该程序参数

如果这两个路径中不含空格的时候就可以正常运行，
如果包含像"D:\Program Files\"或者"G:\Documents and Settings"之类的路径程序就会出问题
原因是在运行行里面如果运行的程序只接收一个参数，参数里面夹一个空格就相当于回车
也就是说，如果运行输入：c:\aa.exe d:\Program Files\tt.txt
其实运行的是：c:\aa.exe d:\Program
这样肯定会出错了

正确的写法应该是：
Process p=Process.Start("\""+t_path.Text.ToString()+"\"","\""+t_file.Text.ToString()+"\"");

这种写法绝对保险。
