将文本重写为文件 [英] reWrite text to file

问题描述

嗨

我用这段代码在文件中写一个字符串（strcontent）

  string  filePath = Server.MapPath（  Emailtesttemplate.html）; 
  string  writeText = StrContent; 
 StreamWriter sw = File.AppendText（filePath）; 
 sw.Write（writeText）; 
 sw.Close（）; 
 
 Response.Write（ < script>）; 
 Response.Write（  window.open（'Emailtesttemplate.html'，'_ blank'））; 
 Response.Write（ < / script>）; 
 

此代码将文本添加到文件末尾！但我需要重写文件...

解决方案

使用WriteAllText（）方法。只需确保您具有覆盖文本文件的相应权限，否则可能会拒绝覆盖。

 System.IO.File.WriteAllText （ @  D：\ path.txt，contents）; 

Hi

Response.Write("</script>");

this code add text to end of file ! but I need to reWrite file ...

解决方案

Use the WriteAllText() method. Just make sure you have the appropriate privileges to overwrite the textfile otherwise the overwrite may be declined.

System.IO.File.WriteAllText (@"D:\path.txt", contents);
