帮助bw.write，写两行以上++ [英] Help in bw.write , writing over 2 lines ++

问题描述

你好

我想创建一个按钮来保存.txt文件，并写出我在源代码中写的内容

hello

I want to create a button to save the .txt and , write what i''ve wrote in the source code

SaveFileDialog sfd = new SaveFileDialog();
            sfd.Filter = "Queries|*.txt";
            sfd.FileName = "blabla";
            sfd.Title = "Save Querie as";
            if (sfd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {
                string path = sfd.FileName;
                BinaryWriter bw = new BinaryWriter(File.Create(path));
                bw.Write(" ");
                bw.Dispose();
            }

但是，bw.Write(");应该是1行

but , bw.Write(" "); should be for 1 line

bw.Write("hi helo code project blabla etc");

但是，如果我要多行怎么办

but , what If I want many lines

bw.Write("Hello
code project
blabla
etc");

但是在那种情况下，它给了我错误.因为它显示我忘记添加);并且，开始了新的损坏行

but in that case , it gives me error. because it reads that I''ve forgot to add "); and , started new corrupted line
Is there any thing should make it?

推荐答案

是的-在需要换行的地方添加"\ n":

Yes - add a "\n" wherever you want a new line:

bw.Write("hi\nhelo\ncode project\nblabla\netc");

将产生:

hi
helo
code project 
blabla
etc

有一个简单的方法来实现.
您可以在字符串前面添加&"号，以表示它是包含回车符的文字.

There is a simple way to do this.
You can add the ampersand in front of your string which indicates that it is a literal including carriage returns.

bw.Write(@"Hello
code project
blabla
etc");
