你可能需要来在PC中的任何位置根据文件名搜索文件。

请参阅：如何使用Visual C＃递归搜索目录 [ ^ ]

您好。你的问题不明显。你执行保存操作吗？

如果你使用saveFileDialog.Create一个按钮并试试这个：

  private   void  GetPathButton_Click（ object  sender，RoutedEventArgs e）
 {
  string  filePath =  ; 
 SaveFileDialog saveFileDialog =  new  SaveFileDialog（）; 
  bool ？ result = saveFileDialog.ShowDialog（）; 
  if （result.Value）
 {
  //  < span class =code-comment>获取完整路径 
 filePath = saveFileDialog.FileName; 
 
  //  获取文件名 
  string  fileName = saveFileDialog.SafeFileName; 
} 
} 

您好，

您可以使用System.IO.FileInfo类

 fileInfo =  new  FileInfo（fileName）; 
 
 fileInfo.DirectoryName;  //  这将提供具有文件的文件夹路径

hi everybody!!
i want to know that how to get the address of a file saved in PC anywhere..

解决方案

You probably need to search a file based on its filename, anywhere in your PC.
See for instance: How to recursively search directories by using Visual C#[^].

Hi. your question isn't obvious. do you perform saving operation ?
if you use saveFileDialog.Create a button and try this:

private void GetPathButton_Click(object sender, RoutedEventArgs e)
       {
           string filePath = "";
           SaveFileDialog saveFileDialog = new SaveFileDialog();
           bool? result = saveFileDialog.ShowDialog();
           if (result.Value)
           {
               //To get full path
               filePath = saveFileDialog.FileName;

               //To get file name
               string fileName = saveFileDialog.SafeFileName;
           }
       }

Hi,
you can use the class System.IO.FileInfo

fileInfo= new FileInfo(fileName);

fileInfo.DirectoryName; //This will give the folder path which is having the file

source...
