将文件保存/复制到另一个目录中

Question

using : asp .net mvc 4.0, c# , vs10

strFilePath holds a path of a existing file in a directory. I want to save/copy the file into my application's uploads directory.

how could i do this. I am trying something foolish, and searching the internet and feeling helpless.

string filePath = "foo.txt";
//var path = Path.Combine(Server.MapPath("~/Uploads"), filePath);
if (System.IO.File.Exists(filePath))
{
    System.IO.File.Copy(filePath, "~/Uploads");
}

Answer 1

~ symbol is not recognized by File.Copy

Convert virtual path to physical path first and then do the copy.

System.IO.File.Copy(filePath, Server.MapPath("~/Uploads"));

Also, You need permission to the folder where you are copying. You may need to Impersonate if the above does not work.
