正则表达式收缩Path.Combine相对于绝对

Question

我有2个文件路径：

绝对的：

/Content/assets2/otherfolder/another/this/

相对

../../../../assets/img/logo.gif

当我做Path.Combine（绝对，相对）时，我得到：

/Content/assets2/otherfolder/another/this/../../../../assets/img/logo.gif

工作正常，但我想得到的是：

/Content/assets/img/logo.gif

我需要一个正则表达式或代码，用相应的文件夹删除“../”：

/Content/assets2/otherfolder/another/this/../../../../assets/img/logo.gif
/Content/assets2/otherfolder/another/../../../assets/img/logo.gif
/Content/assets2/otherfolder/../../assets/img/logo.gif
/Content/assets2/../assets/img/logo.gif

终于进入了：

/Content/assets/img/logo.gif

Answer 1

你不需要正则表达式。实际上，我认为在Regex中以可靠的方式定义是不可能的。而是使用Path.GetFullPath：

string combined = Path.Combine(path1, path2);
string prettyPath = Path.GetFullPath(combined);
