打开保存对话框，选择保存位置，输入文件名保存的代码，能不能给我参考一下。带控件的流程说明也行

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
SaveFileDialog saveFile = new SaveFileDialog();
//saveFile.InitialDirectory = @"C:\";
saveFile.Filter = "文本文件|*.txt|97-2003Word文档|*.doc";
saveFile.FilterIndex = 1;
saveFile.FileName = "文本文件";
if (saveFile.ShowDialog() == DialogResult.OK)
{
string fName = saveFile.FileName;
FileStream fs = File.Open(fName, FileMode.Create);
StreamWriter sw = new StreamWriter(fs);
sw.Write(richTextBox1.Text);
sw.Close();
fs.Close();
}
}
}
