c# - 在 C# 中将 uri 转换为字符串

Question

我有这个代码:

   public static string FindRelativePath(string basePatrh, string targetPath)
    {
        Func<FileSystemInfo, string> getFullName = delegate(FileSystemInfo path)
            {
                string fullName = path.FullName;

                if (path is DirectoryInfo)
                {
                    if (fullName[fullName.Length - 1] != Path.DirectorySeparatorChar)
                    {
                        fullName += Path.DirectorySeparatorChar;
                    }
                }

                return fullName;
            };

        string basePatrhFullName = getFullName(new DirectoryInfo(basePatrh));
        string targetPathFullName = getFullName(new DirectoryInfo(targetPath));

        Uri basePatrhUri = new Uri(basePatrhFullName);
        Uri targetPathUri = new Uri(targetPathFullName);
        Uri relativeUri = basePatrhUri.MakeRelativeUri(targetPathUri);

        return relativeUri.ToString().Replace('/', '\\');
    }

此代码将路径转换为与另一路径相比的相对路径。例如:

   FindRelativePath("c:\test","C;\test\dir1\dir2")

会回来
目录 1\目录 2

代码运行良好，但如果路径中有空格，例如:

  FindRelativePath("c:\test","C;\test\dir1\dir 2")

它返回错误的字符串:

dir1\dir%202

我该如何解决？

您可以使用 Uri.UnescapeDataString这是Uri.EscapeDataString的逆函数.
