【问题描述】：
嗯，首先，我的猜测是我多次调用spritebatch.draw() 方法，但我需要（或者，这是我弄清楚如何做的唯一方法）绘制我的游戏窗口.我会继续转储我的代码。
我的窗口类；

{
WindowSkin = ws;
importedTexture = it;
windowWidth = w;
prevWindowWidth = w;
windowHeight = h;
prevWindowHeight = h;
windowTexture = new RenderTarget2D(g, windowWidth, windowHeight);
currentWindow = windowTexture;
visible = v;

{
s.Draw(currentWindow, pos, new Rectangle(0, 0, windowWidth, windowHeight), Color.White, 0, Vector2.Zero, 1.0f, SpriteEffects.None, 0);
}
public void DrawNewWindow(SpriteBatch s, GraphicsDevice g)
{
g.SetRenderTarget(windowTexture);
g.Clear(Color.Transparent);
s.Begin();
#region Draw Background
for (int w = 3; w < (windowWidth); w += 32)
{
for (int h = 32; h < (windowHeight); h += 32)
{
s.Draw(WindowSkin, new Vector2(w, h), new Rectangle(32, 32, 32, 32), Color.White, 0, Vector2.Zero, 1.0f, SpriteEffects.None, 0);
}
}
#endregion
s.Draw(importedTexture, new Vector2(3, 32), new Rectangle(0, 0, importedTexture.Width, importedTexture.Height), Color.White, 0, Vector2.Zero, 1.0f, SpriteEffects.None, 0);
#region Draw resizables
for (int i = 32; i < (windowWidth - 64); i += 32)
{
s.Draw(WindowSkin, new Vector2(i, 0), new Rectangle(16, 0, 32, 32), Color.White, 0, Vector2.Zero, 1.0f, SpriteEffects.None, 0);
}
for (int i = 32; i < (windowWidth - 32); i += 32)
{
s.Draw(WindowSkin, new Vector2(i, windowHeight - 32), new Rectangle(32, 64, 32, 32), Color.White, 0, Vector2.Zero, 1.0f, SpriteEffects.None, 0);
}
for (int i = 64; i < (windowHeight - 32); i += 32)
{

}

{
s.Draw(WindowSkin, new Vector2(windowWidth - 32, i), new Rectangle(64, 48, 32, 32), Color.White, 0, Vector2.Zero, 1.0f, SpriteEffects.None, 0);
}
#endregion
#region Draw Corners
s.Draw(WindowSkin, new Vector2(0, 0), topLeftRect, Color.White, 0, Vector2.Zero, 1.0f, SpriteEffects.None, 0);
s.Draw(WindowSkin, new Vector2(0, 32), new Rectangle(0, 32, 32, 32), Color.White, 0, Vector2.Zero, 1.0f, SpriteEffects.None, 0);
s.Draw(WindowSkin, new Vector2(windowWidth - 64, 0), topRightRect, Color.White, 0, Vector2.Zero, 1.0f, SpriteEffects.None, 0);
s.Draw(WindowSkin, new Vector2(windowWidth - 32, 32), new Rectangle(64, 32, 32, 32), Color.White, 0, Vector2.Zero, 1.0f, SpriteEffects.None, 0);
s.Draw(WindowSkin, new Vector2(windowWidth - 32, 0), buttonRect, Color.White, 0, Vector2.Zero, 1.0f, SpriteEffects.None, 0);
s.Draw(WindowSkin, new Vector2(0, windowHeight - 32), botLeftRect, Color.White, 0, Vector2.Zero, 1.0f, SpriteEffects.None, 0);
s.Draw(WindowSkin, new Vector2(windowWidth - 32, windowHeight - 32), botRightRect, Color.White, 0, Vector2.Zero, 1.0f, SpriteEffects.None, 0);
#endregion
s.End();
currentWindow = windowTexture;
}
}
}
我的 Draw() 方法；
protected override void Draw(GameTime gameTime)
{
window1.DrawNewWindow(spriteBatch, GraphicsDevice);
window1.drawNew = false;
GraphicsDevice.SetRenderTarget(null);
GraphicsDevice.Clear(Color.CornflowerBlue);
spriteBatch.Begin(SpriteSortMode.Deferred,
BlendState.AlphaBlend,
SamplerState.PointClamp,
null,
null,
null);
window1.Draw(spriteBatch, GraphicsDevice);
spriteBatch.End();
base.Draw(gameTime);
}
这一切都很好，并针对我的小窗皮纹理等进行了配置。唯一的问题是它会有点滞后，然后在运行它大约一分钟后完全崩溃。它会抛出一个Out Of Memory Exception，但我不知道也找不到与 spritebatch 相关的任何其他主题或帖子。有人对我如何使这项工作不占用太多内存有任何建议吗？我认为这是一种简单、经济有效的绘制窗口的方法。我只是不确定如何减少我的绘图调用，或者恢复任何内存。
