充分利用StreamWriter的文件大小 [英] Getting the file size from StreamWriter

问题描述

using (var writer = File.CreateText(fullFilePath))
{
   file.Write(fileContent);
}

由于上面的代码，可以将文件大小从<$ C $称为C>的StreamWriter ？

推荐答案

是的，你可以尝试以下

long length = writer.BaseStream.Length;//will give unexpected output if autoflush is false and write has been called just before

请注意： writer.BaseStream.Length 属性可以从<返回意外的结果code>的StreamWriter 不立即写。它缓存需要那么得到期望的输出自动冲洗= TRUE

Note: writer.BaseStream.Length property can return unexpected results since StreamWriter doesn't write immediately. It caches so to get expected output you need AutoFlush = true

writer.AutoFlush = true; or writer.Flush();
long length = writer.BaseStream.Length;//will give expected output
