GetPathRoot

GetPathRoot的用途是用來獲取指定路徑的根目錄信息。例如C語言中：string path = @"\mydir\";string fileName = "myfile.ext";string fullPath = @"C:\mydir\myfile.ext";string pathRoot。

用途

獲取指定路徑的根目錄信息。

c#舉例

string path = @"\mydir\";

string fileName = "myfile.ext";

string fullPath = @"C:\mydir\myfile.ext";

string pathRoot;

pathRoot = Path.GetPathRoot(path);

Console.WriteLine("GetPathRoot('{0}') returns '{1}'", path, pathRoot);

pathRoot = Path.GetPathRoot(fileName);

Console.WriteLine("GetPathRoot('{0}') returns '{1}'", fileName, pathRoot);

pathRoot = Path.GetPathRoot(fullPath);

Console.WriteLine("GetPathRoot('{0}') returns '{1}'", fullPath, pathRoot);

// This code produces output similar to the following:

//

// GetPathRoot('\mydir\') returns '\'

// GetPathRoot('myfile.ext') returns ''

// GetPathRoot('C:\mydir\myfile.ext') returns 'C:\'
