Getting last field of a Path?
DirectoryInfo di = new DirectoryInfo("Your path");

String lastField = di.Name;

string folderName = new DirectoryInfo(@ "D:SolutionsTestPluginPluginsDashboardSimu").name;

string folderName = Path.GetFileName(@ "D:SolutionsTestPluginPluginsDashboardSimu");

using System.IO;

string lastComponent
    = Path.GetFileName(@"D:SolutionsTestPluginPluginsDashboardSimu");
// Now lastComponent is "DashBoardSimu".

string path = @"D:SolutionsTestPluginPluginsDashboardSimu";
string file = Path.GetFileName(path);

string dir = @"D:SolutionsTestPluginPlugins", file = "DashboardSimu";
string path = Path.Combine(dir, file);

string dd = @"D:SolutionsTestPluginPluginsDashboardSimu";
    string[] a =  dd.Split('\');
    Console.WriteLine(a[a.Length -1]);
