比较两个文件夹与SymmetricDifference非相同的文件？

Question

我比较非完全相同的文件，两个文件夹具有对称差，写的长度和目录名到一个文本文件...但它是写像

5506  D:\Trial\codegenpath\ramcovm247_portal_765\EDKPLAjaxCodeGen.log 
5857  D:\Trial\codegenpath\ramcovm247_portal_765\EDKService.log 
3741  D:\Trial\codegenpath\ramcovm247_portal_765\EDKTypes.log 
10644  D:\Trial\zippedpath\ramcovm247_portal_765\EDKPLAjaxCodeGen.log 
11714  D:\Trial\zippedpath\ramcovm247_portal_765\EDKService.log 
7482  D:\Trial\zippedpath\ramcovm247_portal_765\EDKTypes.log 

，但我需要其他这样的后写一个

5506  D:\Trial\codegenpath\ramcovm247_portal_765\EDKPLAjaxCodeGen.log 
10644  D:\Trial\zippedpath\ramcovm247_portal_765\EDKPLAjaxCodeGen.log 
5857  D:\Trial\codegenpath\ramcovm247_portal_765\EDKService.log 
11714  D:\Trial\zippedpath\ramcovm247_portal_765\EDKService.log 
3741  D:\Trial\codegenpath\ramcovm247_portal_765\EDKTypes.log 
7482  D:\Trial\zippedpath\ramcovm247_portal_765\EDKTypes.log 

这里是我的代码

var queryList1Only2 = (from file in list1 select file).Except(list2, myFileCompare1); 
var queryList1Only22 = (from file in list2 select file).Except(list1, myFileCompare1); 
var difference = queryList1Only2.ToHashSet(); 
difference.SymmetricExceptWith(queryList1Only22); 
foreach (var v in difference) 
     { 
      dest.WriteLine(v.Length + "  " + v.FullName); 

     } 

和

public class FileCompareLength : System.Collections.Generic.IEqualityComparer<System.IO.FileInfo> 
     { 
      public FileCompareLength() { } 
      public bool Equals(System.IO.FileInfo f1, System.IO.FileInfo f2) 
      { 
       return (f1.Length == f2.Length); 
      } 
      public int GetHashCode(System.IO.FileInfo fi) 
      { 
       string s = String.Format("{0}", fi.Length); 
       return s.GetHashCode(); 
      } 
     } 

任何建议？
