如何将字符串解析为StreamWriter对象 [英] How to Parse a string to a StreamWriter object

问题描述

我打开了大量文件句柄(约500个).

这些文件句柄的名称是文件路径，例如

C:\ myFile001.txt

现在，我希望向其中一个文件中写入一些数据:

我尝试

I have a large number of file handles open (c. 500).

the names of the these file handles are file paths eg

C:\myFile001.txt

I now wish to write some data to one of the files:

I try

StreamWriter handle = "C:\myFile001.txt";

handle.WriteLine(message.ToString());

但是，我得到了错误:

无法将类型字符串"隐式转换为"System.IO.StreamWriter"

我已经尝试了从字符串到StreamWriter的简单转换，但这也不起作用.

感谢您的帮助！

however, I get the error:

Cannot implicitly convert type ''string'' to ''System.IO.StreamWriter''

I have tried a simple cast from string to StreamWriter, but that doesnt work either.

Any help gratefully recieved!

推荐答案

0)为什么您同时打开了这么多文件?那是极其低效的.

1)您发布的第一行代码应如下所示:

0) WHY do you have so many files open at the same time? That''s extremely inefficient.

1) The first line of code you posted should look like this:

StreamWriter handle = new StreamWriter("C:\\myfile001.txt");
