推荐答案

这很自然，因为您试图两次打开文件:
的目的是什么

That''s natural since you''re trying to open the file two times: What''s the purpose of the

using (FileStream fs = File.Create(path))

是否再次打开文件(使用new StreamWriter("C:\\mytest.txt");)?

例如，请参见:"C#使用StreamWriter" [ ^ ].

if you then open again the file (with new StreamWriter("C:\\mytest.txt");)?

See, for instance: "C# Using StreamWriter"[^].

您遇到的问题是因为您刚刚使用以下行创建了文件:

The issue you are getting is because you''ve just created the file using the line:

using (FileStream fs = File.Create(path))

此时文件已打开，然后您尝试使用以下命令再次打开同一文件:

The file is open at this point, and you then attempt to open the same file again using:

TextWriter sw = new StreamWriter("C:\\mytest.txt");//error is coming here

使用其中一个.两者都不是.

Use one or the other. Not both.
