Monogame 内容加载异常

Question

在 Monogame 中制作了一个游戏，但是当我运行它时，我得到了大量的输出，说缺少一堆 DLL。游戏运行良好，因为它不会崩溃，但当我遇到其中一个错误时，我会冻结一秒钟。它通常在我加载资产时发生，但在该资产已加载时不会再次发生。

这是一次运行的输出。

The program '[21932] Rougelike.exe: Program Trace' has exited with code 0 (0x0).
The program '[21932] Rougelike.exe' has exited with code -1 (0xffffffff).

这是我用来加载资源的代码：

GurmLibX.Framework.GameGLX.cs：游戏

Core.Content.Manager = Content;

GurmLibX.Framework.Content.cs

public static ContentManager Manager = null;

public static string RootDirectory
{
    get { return Manager.RootDirectory; }
    set { Manager.RootDirectory = value; }
}

public static T Load<T>(string assetName)
{
    return Manager.Load<T>(assetName);
}

使用如下：

SpriteFont font = Content.Load<SpriteFont>("fonts/someFont");

你猜到为什么会这样吗？

Answer 1

首先让我们看看错误。

“Rougelike.exe”（CLR v4.0.30319：Rougelike.exe）：已加载“D:\Dropbox\Projects\GurmLibX\Rougelike\bin\Windows\Release\SharpDX.DXGI.dll”。无法找到或打开 PDB 文件。

我相信这些“无法找到或打开 PDB 文件”错误无需担心。在 Visual Studio 中调试时会使用 PDB 文件，因此您无法单步执行这些 DLL 中包含的代码可能会有点烦人，但除此之外它不会影响您的游戏。

抛出异常：mscorlib.dll 中的“System.IO.FileNotFoundException”

抛出异常：MonoGame.Framework.dll 中的“Microsoft.Xna.Framework.Content.ContentLoadException”

我认为这两者密切相关。我相信第一个异常触发了 MonoGame 内部深处的第二个异常。

基本上，当Content.Load 方法试图加载您的内容文件时，找不到它们。

SpriteFont font = Content.Load<SpriteFont>("fonts/someFont");

通常发生的情况是MonoGame's Content Pipeline tool 在构建时处理内容，并将内容文件输出到可执行文件旁边的 Content 文件夹。

文件夹的确切路径因设置而异，但在您的情况下（根据错误消息），它应该类似于：

D:\Dropbox\Projects\GurmLibX\Rougelike\bin\Windows\Release\Content

查看该文件夹，看看是否可以找到 Pipeline 生成的 XNB 文件。

Answer 2

您使用的是 VS 2017 吗？您可能会遇到一些问题，就我而言，我单独启动了 MonoGame 的 Content Pipeline 工具并构建了所有 Content 文件夹 Add Existing Item > (Your Sprite) > Build。可能不是最好的解决方案，但它可以让你工作;)
