修复建议:加一个catch

建议:

public static void DeleteMod(ModObj mod)
{
    try {
        string name = new FileInfo(mod.Local).Name;
        foreach (var item in mod.Game.Mods)
        {
            if (item.Value.File == name)
            {
                mod.Game.Mods.Remove(item.Key);
                mod.Game.SaveModInfo();
                break;
            }
        }
        mod.Delete();
    } catch (Exception e) {
        // do sth like showing a dialog
    }
}

本人不会C#,我是按Java写的
