//用 RichTextBox 自带的 LadFile 方法。
if (openFile.ShowDialog() == DialogResult.OK)
{
rtbText.LoadFile(openFile.FileName, RichTextBoxStreamType.RichText);
}
试试这段代码：
if (openFile.ShowDialog() == DialogResult.OK)
{
string rtf = File.ReadAllText(openFile.FileName);
rtbText.Rtf = rtf.ReadToEnd().Replace("\r\n", "\n");
}
