在某个特定位置写入文件 [英] Writing in a File at Some Specific Position

问题描述

如果我们逐行阅读文件，请使用Stream Reader。



现在如果我想在特定位置使用StreamWriter写文件那么如何当我出现在那个特定位置时，我会知道这一点。



任何人都可以通过示例/代码片段分享说明吗？？

When by Using the Stream Reader if we read the File Line By Line.

Now If I wants to Write The File using StreamWriter At Some Specific Position Then How I will Come to Know about That When I was Present at that Specific Position.

Can Anyone Please Share The Explanation with an Example/Code Snippet ..?

推荐答案

你可以使用StreamWriter类的BaseStream属性的Seek方法跳转到该位置。



示例代码

You can use the Seek method of the BaseStream property of StreamWriter class to jump to the location.

sample code

FileStream stream = new FileStream(@"filename.txt",FileMode.Open,FileAccess.ReadWrite);
StreamWriter writer = new StreamWriter(stream);

writer.BaseStream.Seek(10000, SeekOrigin.Begin); // where 10000 is the offset to jump
writer.WriteLine("new Test starts here");
