從saveFileDialog獲取沒有文件名的路徑？

Question

我試圖從SaveFileDialog我的路沒有我的文件名，以創建一個DirectoryInfo對象

private void btnBrowseCapture_Click(object sender, EventArgs e) 
{ 
    SaveFileDialog saveFileDialogBrowse2 = new SaveFileDialog(); 
    saveFileDialogBrowse2.Filter = "Pcap file|*.pcap"; 
    saveFileDialogBrowse2.Title = "Save an pcap File"; 
    saveFileDialogBrowse2.ShowDialog(); 

    if (saveFileDialogBrowse2.FileName != "") 
    { 
     string str = saveFileDialogBrowse2.FileName; 

    } 
} 

Answer 1

使用System.IO.FileInfo.DirectoryName屬性來獲取文件的目錄的完整路徑。

---

string fileName = @"C:\TMP\log.txt"; 
FileInfo fileInfo = new FileInfo(fileName); 

Console.WriteLine(fileInfo.DirectoryName); // Output: "C:\TMP" 

---

使用你的例子：

string str = saveFileDialogBrowse2.FileName; 

FileInfo fileInfo = new FileInfo(str); 
Console.WriteLine(fileInfo.DirectoryName); 

Answer 2

string fileName = @"C:\TMP\log.txt"; 
FileInfo fileInfo = new FileInfo(fileName); 

Console.WriteLine(fileInfo.DirectoryName); 

Answer 3

您可以使用System.IO.Path.GetDirectoryName方法：

Console.WriteLine(System.IO.Path.GetDirectoryName(Filename)); 

Answer 4

您還可以使用System.IO.Path.GetDirectoryName用於此目的

System.IO.Path.GetDirectoryName(filePath)
