C#：用保存对话框保存成文件，总提示文件正在使用，紧急求助……

SaveFileDialog sfd = new SaveFileDialog();

sfd.Filter = "文本文件(*.txt)|*.txt|全部文件(*.*)|*.*";
sfd.InitialDirectory = "D:\\";
sfd.FilterIndex = 0;

sfd.InitialDirectory = "D:\\";
sfd.FilterIndex = 0;
sfd.RestoreDirectory = true;

if (sfd.ShowDialog() == DialogResult.OK)
{
richTextBox1.SaveFile(@sfd.FileName, RichTextBoxStreamType.PlainText); //文本编码格式

}

SaveFileDialog sfd = new SaveFileDialog();

sfd.Filter = "文本文件(*.txt)|*.txt|全部文件(*.*)|*.*";
sfd.InitialDirectory = "D:\\";
sfd.FilterIndex = 0;
sfd.RestoreDirectory = true;
