C# 在c中将uri转换为字符串#

我有以下代码：

   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('/', '\\');
    }

将返回
dir1\dir2

代码运行良好，但如果路径中有空间，例如：

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

它返回错误的字符串：

dir1\dir%202

---

我怎样才能修好它

返回的字符串没有错误%20表示可以使用的

dir

2
之间的空格。
%20”是US-ASCII空格字符的转义编码
因此，您必须像Uri.UnescapeDataString一样对其进行Unescape

dir1\dir%202

public static string FindRelativePath(string basePath, string targetPath)
{
           return Uri.UnescapeDataString(
                basePath.MakeRelativeUri(targetPath)
                    .ToString()
                    .Replace('/', Path.DirectorySeparatorChar)
                );
}
