Answer 1

您也可以使用System.IO.Path.GetDirectoryName来实现此目的

System.IO.Path.GetDirectoryName(filePath)

Answer 2

Use System.IO.FileInfo.DirectoryName property to get the full path of the directory of a file.

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

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

Using your example:

string str = saveFileDialogBrowse2.FileName;

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

Answer 3

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

Console.WriteLine(fileInfo.DirectoryName);

Answer 4

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

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