How to download a file from cloud and to get the path in C#

dhanu shree

I want to download a file from cloud and i want to get the path of that downloaded file through C# programming.
I'm able to fetch file by passing the path through a variable. But I need to fetch the file without passing file path as variable.could anyone help me on this.
var folderPath = "C:\\Users\\T430\\source\\repos\\download\\download\\bin\\Debug";
foreach (string file in Directory.EnumerateFiles(folderPath, "sample*.xml"))
{
string contents = File.ReadAllText(file);
Console.WriteLine(contents);
Console.ReadLine();
}

First of all, that path is not for cloud. Secondly, the complete path is needed for each file to be accessed. Otherwise, you need to input that path as a base address for the request (if speaking in context of the cloud and API). So, please share the code that you are using to access files from "cloud". This code is for local directory.
