    int IntFileCount = Directory.GetFiles(Server.MapPath(StrDirectory), "*.*", SearchOption.TopDirectoryOnly).Length;
    Random Random1 = new Random();
    IntFileCount = IntFileCount + 1;
    GetRandomImage = StrDirectory + StrFileName + Random1.Next(1, IntFileCount) + ".png";
    Response.Write(GetRandomImage);

# requires a call to DataBind() on the control.

protected string GetRandomImage(string StrDirectory, string StrFileName)
{
    Response.Write("Test: GetRandomImage True");
    string GetRandomImage;
    int IntFileCount = Directory.GetFiles(Server.MapPath(StrDirectory), "*.*", SearchOption.TopDirectoryOnly).Length;
    Random Random1 = new Random();
    IntFileCount = IntFileCount + 1;
    GetRandomImage = StrDirectory + StrFileName + Random1.Next(1, IntFileCount) + ".png";
    Response.Write(GetRandomImage);
    return GetRandomImage;
}

You can call it with the fully qualified namespace if its a static method or with a this if its a page method. Use an equal sign instead of hash

<%= this.GetRandomImage("images/random/","random_") %>
