比较两个文件夹内同名文件内容是否相同



string sourcePathA = @"patha"  

string sourcePathB = @"pathb";  

string[] filenames = Directory.GetFiles(sourceParhA) ; 

string[] directories = Directory.GetDirectories(sourcePathA);  

foreach(string file in fileNames)

{

     string useName = file.Substring(fie.LastIndexOf('\\')+1);

     string comparefile = sourcePathB + "\\" + useName;

     if(File.Exists(comparefile))

    {

         FileStream fsa = new FIlesStream(file,FileMode.Open,FIleAccess.Read);

         StreamReader sra = new StreamReader(fsa,Encoding.Default);

         string linea = sra.ReadToEnd();
