如何在C#[duplicate]中获得从一条路径到另一条路径的相对路径

Uri 作品:

Uri path1 = new Uri(@"c:\dir1\dir2\");
Uri path2 = new Uri(@"c:\dir1\dir3\file1.txt");
Uri diff = path1.MakeRelativeUri(path2);
string relPath = diff.OriginalString;

您还可以导入 PathRelativePathTo 函数并调用它。

例如。:

using System.Runtime.InteropServices;

public static class Util
{
  [DllImport( "shlwapi.dll", EntryPoint = "PathRelativePathTo" )]
  protected static extern bool PathRelativePathTo( StringBuilder lpszDst,
      string from, UInt32 attrFrom,
      string to, UInt32 attrTo );

  public static string GetRelativePath( string from, string to )
  {
    StringBuilder builder = new StringBuilder( 1024 );
    bool result = PathRelativePathTo( builder, from, 0, to, 0 );
    return builder.ToString();
  }
}
