c# - 异常: System. ComponentModel.Win32Exception : Invalid data at System. Diagnostics.Process.Start_shell

Question

我正在linux环境下工作，使用Mono进行开发。我有一个 C# 项目，我想在其中启动另一个应用程序/可执行文件。代码片段如下:

string pathToDB = @"""/root/somefolder/anotherfolder/""";
                        Process process = new Process();
                        process.StartInfo.FileName = @"/root/somefolder/filename";
                        process.StartInfo.Arguments = @"""" + pathToDB + @"""" + "$" + contents + "$" + "documentTerms";
                        process.Start();    

我正在传递三(3)个参数。第一个是文件夹路径，第二个是我用字符串内容表示的一些文本数据，第三个是一些硬编码文本。当我运行这个程序时，它给我以下异常/错误:

CreateProcess: Unfinished quote.

  at XapianTest.SimpleIndex.Main (System.String[] argv) [0x00023] in /root/Projects/XapianTest/XapianTest/SimpleIndex.cs:51    

我做错了什么! 请任何人帮助我...

提前致谢...

参数之间需要空格。试试这个:

process.StartInfo.Arguments = @"""" + pathToDB + @""" ""$" + contents + @"$"" " + "documentTerms";
