C# 如何提取SaveFileDialog的保存路径

 1 public TestOne() 
 2 { 
 3 InitializeComponent(); 
 4 SaveFileDialog();//调用打开SaveFileDialog 保存对话框 
 5 } 
 6 
 7 #region 保存对话框 
 8 private void SaveFileDialog() 
 9 { 
10 //string localFilePath, fileNameExt, newFileName, FilePath; 
11 SaveFileDialog saveFileDialog1 = new SaveFileDialog(); 
12 
13 //设置文件类型 
14 saveFileDialog1.Filter = " txt files(*.txt)|*.txt|All files(*.*)|*.*"; 
15 
16 //设置默认文件类型显示顺序 
17 saveFileDialog1.FilterIndex = 2; 
18 
19 //保存对话框是否记忆上次打开的目录 
20 saveFileDialog1.RestoreDirectory = true; 
21 
22 //点了保存按钮进入 
23 if (saveFileDialog1.ShowDialog() == DialogResult.OK) 
24 { 
25   //获得文件路径 
26   //localFilePath = saveFileDialog1.FileName.ToString(); 
27 
28   //获取文件名，不带路径 
29   //fileNameExt = localFilePath.Substring(localFilePath.LastIndexOf("\\") + 1); 
30 
31   //获取文件路径，不带文件名 
32   //FilePath = localFilePath.Substring(0, localFilePath.LastIndexOf("\\")); 
33 
34   //给文件名前加上时间 
35   //newFileName = DateTime.Now.ToString("yyyyMMdd") + fileNameExt; 
36 
37   //在文件名里加字符 
38   //saveFileDialog1.FileName.Insert(1,"dameng"); 
39     
40   System.IO.FileStream fs = (System.IO.FileStream)saveFileDialog1.OpenFile();//输出文件 
41 
42                       //fs输出带文字或图片的文件，就看需求了 
43 }
