C#紧凑框架友好的命令行解析器 [英] C# Compact-Framework friendly command line parser

问题描述

我阅读了以下问题: .NET的命令行解析器.

我以为这是我想要的，但是库命令行解析器库并不紧凑框架友好...

I thought that was what I was looking for, but the library Command Line Parser Library is not Compact framework friendly...

我 REALLY 不想编写CL解析器，由于这个不幸的尝试，我一直在偏离我的小应用程序的真实用途.

I REALLY don't want to write a CL parser and I have been drifting away from the real purpose of my little app because of this unfortunate trial.

有人知道适合紧凑框架的库吗? (最好具有上述提到的简单性和功能性)
无论版本2还是3.5

Does someone know of a library that fits the compact-framework? (preferably with simplicity and functionality like the one mentioned above)
Does not matter whether version 2 or 3.5

推荐答案

这就是我正在使用的.我从某个地方借来的，但不确定在哪里:

This is what I'm using. I borrowed it from somewhere, but not sure where:

using System.Text.RegularExpressions;

        string[] parts;
