use follow fucntion... to generate random string and add it to you filename in
File.SaveAs() function.

public static string RandomString(int size)
{

StringBuilder builder = new StringBuilder();
for(int i=0; i < size; i++)
{

//26 letters in the alfabet, ascii + 65 for the capital letters
builder.Append(Convert.ToChar(Convert.ToInt32(Math.Floor(26 * _random.NextDouble() + 65))));

}
return builder.ToString();

}
