我找到了直接从文件加载图像的方式，但我加载的图像是蓝色的（原始为绿色）。我想它保存的方式很糟糕，所以我用photoshop保存了它，但没有任何改变。我想我的程序工作不好。我怎样才能改变它，是从文件中加载图像的好方法？ 位图的Texture2D方法：XNA和从文件加载图像
public static Texture2D GetTexture2DFromBitmap(GraphicsDevice device, Bitmap bitmap)
{
Texture2D tex = new Texture2D(device, bitmap.Width, bitmap.Height);
System.Drawing.Imaging.BitmapData data = bitmap.LockBits(new System.Drawing.Rectangle(0, 0, bitmap.Width, bitmap.Height), System.Drawing.Imaging.ImageLockMode.ReadOnly, bitmap.PixelFormat);
int bufferSize = data.Height * data.Stride;
byte[] bytes = new byte[bufferSize];
System.Runtime.InteropServices.Marshal.Copy(data.Scan0, bytes, 0, bytes.Length);
tex.SetData(bytes);
bitmap.UnlockBits(data);
return tex;
}
导入图像行：
backgroundTexture = Tools.GetTexture2DFromBitmap(device, (System.Drawing.Bitmap)System.Drawing.Image.FromFile(@"1.bmp", false));
溺水纹理的方法：
spriteBatch.Begin();
Rectangle screenRectangle = new Rectangle(0, 0, screenWidth, screenHeight);
spriteBatch.Draw(backgroundTexture, screenRectangle, Color.White);
spriteBatch.End();
