Use DateTime.Now.Ticks.ToString() or DateTime.Now.ToFileTime().ToString() to generate random number.

Here 

using System;
using System.Text;

public string RandomString (Random r, int len)
{
    string str
         = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890";
    StringBuilder sb = new StringBuilder();

    while ((len--)> 0)
        sb.Append(str[(int)(r.NextDouble() * str.Length)]);

    return sb.ToString();
}

Instead of generating random number and a string, you should use GUID. That will be unique as well. 

string val  = Guid.NewGuid().ToString();
