将RichTextBox的内容写入文件

感谢彼得·林德霍尔姆,他在评论中给了我正确的答案。

你试过savefile方法了吗 位于richtextbox本身? http://msdn.microsoft.com/en-us/library/system.windows.forms.richtextbox.savefile(VS.71).aspx

我有同样的问题-但不想保存为richtextbox-只是一个标准的简单的txt文件,可以很容易地在记事本中读取和编辑。

由于某种原因,streamwriter类没有将\n写入文件中(仍然不确定原因-您可能会认为是这样):)

因此,一个简单的解决方案是用\r\n手动替换\n并按预期完美工作。

请参见下面的代码截图:

if ((myStream = ScriptFileSaveDB.OpenFile()) != null)
{
    using (StreamWriter sr = new StreamWriter(myStream))
    {
        //Since \n (newlines) are not being written correctly as \r\n
        //Go thru Text and replace all "\n" with \r\n
        tempStr = ScriptProgramWindowRTB.Text;
        tempStr = tempStr.Replace("\n", "\r\n");
        sr.Write(tempStr);
    }

private void btnToFile_Click(object sender, EventArgs e)
{
    //Don't work as desired
    SaveFileDialog saveFileDialog1 = new SaveFileDialog();
    saveFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
    saveFileDialog1.FilterIndex = 2;
    saveFileDialog1.RestoreDirectory = true;

    if (saveFileDialog1.ShowDialog() == DialogResult.OK)
    {
        System.IO.StreamWriter SW = new System.IO.StreamWriter(
            saveFileDialog1.FileName, false, Encoding.ASCII);
        SW.Write(txtClass.Text);
        SW.Close();
    }
}
