RichTextBox获取文字文本

Question

I'm trying to save the text from my RichTextBox to a text file. However, upon doing so, the new lines in the RTB aren't considered "new lines" and hence a \\n isn't appended in the text file, so if I have:

This is a test
line of content

It will write to the text file as:

This is a testline of content

I'm saving the text the following way:

File.WriteAllText(currentFile, richTextBox1.Text);

I'm just wondering if there's any solution for this. Thanks.

Answer 1

Try this:

StreamWriter sw = File.CreateText(currentFile);
for (int i = 0; i < richTextBox1.Lines.Length; i++)
{
    sw.WriteLine(richTextBox1.Lines[i]);
}
sw.Flush();
sw.Close();

or use the rtb.SaveFile() method: http://msdn.microsoft.com/en-us/library/system.windows.forms.richtextbox.savefile%28VS.71%29.aspx

请改用构建的SaveFile方法。

richTextBox1.SaveFile(currentFile, RichTextBoxStreamType.PlainText);
