在Texture2D XNA列表中加载纹理

Question

I created the

List<Texture2D> paddles = new List<Texture2D>();

and in the LoadContent() in the XNA, I wanted to load a single texture so I did it like this:

paddles[0] = Content.Load<Texture2D>("Graphics/First Paddle");
paddles[1] = Content.Load<Texture2D>("Graphics/Second Paddle");

but I have received this error at this line of code when I tried to run it paddles[0] = Content.Load<Texture2D>("Graphics/First Paddle");

An unhandled exception of type 'System.ArgumentOutOfRangeException' occurred in mscorlib.dll Additional information: Index was out of range. Must be non-negative and less than the size of the collection.

How to solve this?

Thank you

You're trying to reference list items that currently don't exist, and therefore, you're getting the given error. Try using the below:

paddles.Add(Content.Load<Texture2D>("Graphics/First Paddle"));

Note in the future that a list never has its objects instantiated, so you need to use Add to directly add to the list.
