当路径包含＃

时创建零件Uri我使用下面的代码压缩文件。我发现当被压缩的路径中的文件夹包含散列（＃）时，CreatePartUri（uri）会抛出异常：当路径包含＃

零件URI不能包含片段组件。

由于我无法改变文件夹名称，我该如何转义路径中的＃符号才能正确创建Uri？

       if (File.Exists(targetFilePath)) 
       { 
        File.Delete(targetFilePath); 
       } 
       string packageRelationshipType = 
         @"http://schemas.openxmlformats.org/" + 
         @"package/2007/relationships/htmx/root-html"; 

       CompressionOption compressionOption = CompressionOption.Maximum; 

       using (Package package = Package.Open(targetFilePath,

       { 
        string fileName = @"\#TestFolder\TestFile.txt"; 
        string filePathOnServer = @"C:\" + fileName; 

        Uri uri = new Uri(fileName, UriKind.Relative);

       target.Write(buf, 0, bytesRead);

['HttpUtility.UrlEncode']（http://msdn.microsoft.com/en-us/library/system .web.httputility.urlencode.aspx）？ – Oded

@Oded使用UrlEncode可以避开异常，但会导致CreateRelationship引发“无效的URI：无法解析主机名”。 – HaemEternal

System.IO.Packaging程序不允许 “＃” 在名字
