从包含文件名的路径中获取没有文件名的完整路径

Question

Is there anything built into System.IO.Path that gives me just the filepath?

For example, if I have a string

@"c:\\webserver\\public\\myCompany\\configs\\promo.xml",

is there any BCL method that will give me

"c:\\webserver\\public\\myCompany\\configs\\"?

Answer 1

Path.GetDirectoryName() ... but you need to know that the path you are passing to it does contain a file name; it simply removes the final bit from the path, whether it is a file name or directory name (it actually has no idea which).

You could validate first by testing File.Exists() and/or Directory.Exists() on your path first to see if you need to call Path.GetDirectoryName

Answer 2

Console.WriteLine(Path.GetDirectoryName(@"C:\hello\my\dear\world.hm")); 

Answer 3

Path.GetDirectoryName()返回目录名称，因此对于您想要的（带有尾随反实线字符），您可以调用Path.GetDirectoryName(filePath) + Path.DirectorySeparatorChar 。

Answer 4

    string fileAndPath = @"c:\webserver\public\myCompany\configs\promo.xml";

    string currentDirectory = Path.GetDirectoryName(fileAndPath);

    string fullPathOnly = Path.GetFullPath(currentDirectory);

currentDirectory: c:\\webserver\\public\\myCompany\\configs

fullPathOnly: c:\\webserver\\public\\myCompany\\configs

Answer 5

Use GetParent() as shown, works nicely. Add error checking as you need.

var fn = openFileDialogSapTable.FileName;
var currentPath = Path.GetFullPath( fn );
currentPath = Directory.GetParent(currentPath).FullName;

Answer 6

I used this and it works well:

string[] filePaths = Directory.GetFiles(Path.GetDirectoryName(dialog.FileName));

foreach (string file in filePaths)
{   
    if (comboBox1.SelectedItem.ToString() == "")
    {
        if (file.Contains("c"))
        {
            comboBox2.Items.Add(Path.GetFileName(file));
        }
    }
}
