在Visual C＃和XNA中复制精灵数组

Question

I am developing a Uno card game using Visual C# 2010 and XNA 4.0. I have created an array of 108 element of all the Uno Cards as the array elements.

Now I want to assign random 7 cards to each of the 4 players at the begining of the game. So I am creating a random number and then assigning the card at that nmber to a player.

    for (int i = 0; i < 7; i++)
        {
            int r = rnd.Next(108);
            if (vis[r] != 1)  //vis[] is an array to checkk visited elements
            {

              //  u[i] = Content.Load<Texture2D>("toString.Allcards[r]");
                u[i]=Content.Load<Texture2D>(ToString("Allcards[r]"));
            } 

This is not working, please help.

假设“ Allcards [r]”保存卡片的纹理（即，Allcards [1] ==“黑桃A”，并且在您的项目中有一个名为黑桃A的纹理），则可能需要这样：

u[i]=Content.Load<Texture2D>(Allcards[r]);

    for (int i = 0; i < 7; i++)
            {
                int r = rnd.Next(108);
                if (vis[r] != 1)  //vis[] is an array to checkk visited elements
                {

                  //  u[i] = Content.Load<Texture2D>("toString.Allcards[r]");
                    u[i]=Content.Load<Texture2D>(Allcards[r].ToString());
                } 
            }

You want Content.Load<Texture2D>(Allcards[r]); assuming that Allcards is an array of strings. If Allcards is an array of Texture2D objects, then Content.Load is unnecessary because you've already loaded it; you can use u[i] = Allcards[r] .

Having said that, you probably don't want to just give the texture to the player; you'll want to give them the actual card. I'd suggest creating a Card class and assigning textures to that, along with some useful info like an ID, and maybe some properties to explain what it does.
