Like in image i want to create A->B->C and D inside B all at once without loop. Is there any way to achieve it in C#

    Directory.CreateDirectory will create all directories in the given path, including any subdirectories.
using System.IO;
var paths = new [] { "F:\\A\\B\\C", "F:\\A\\B\\D" };
foreach (var path in paths) {
    try {
        // Determine whether the directory exists.
        if (Directory.Exists(path)) {
            Console.WriteLine($"Skipping path '{path}' because it exists already.");
            continue;
        }
        // Try to create the directory.
        var di = Directory.CreateDirectory(path);
        Console.WriteLine($"Created path '{path}' successfully at {Directory.GetCreationTime(path)}.");
    }
    catch (Exception e) {
        Console.WriteLine($"The process failed: {e}");
    }
}
 
    
    Try This code.
 private string GetUploadFileFolderPath()
    {
        string struploadUserImageFolderPath ="~/A/";
        string strGetStockUploadFolderName ="C";
        string strfullFolderPath = "~/A/" + "B" + "/" + strGetStockUploadFolderName + "/";
        return strfullFolderPath;
    }
 struploadUserImageFolderPath = GetUploadFileFolderPath();    // file path
                    if (!Directory.Exists(Server.MapPath(struploadUserImageFolderPath)))
                    {
                        Directory.CreateDirectory(Server.MapPath(struploadUserImageFolderPath));
                    }
