WPF - 检查资源不存在结构化异常处理 [英] WPF - check resource exists without structured exception handling

问题描述

有没有什么办法来检查装配体中的一个资源存在，而无需使用异常处理？我目前正在加载的图像来自几个组件，如果他们不存在，那么我处理IOException异常，导致相当多的开销。

Is there any way to check if a resource exists in an assembly without having to use exception handling? I'm currently loading images from several assemblies, and if they don't exist then I'm handling the IOException, which causes quite a bit of overhead.

推荐答案

请问这样的事情对你的工作？

Would something like this work for you?

// Member Variable
string [] resourceNames;

// Function
Boolean ResourceExists(string resourceName)
{
    if (resourceNames == null)
    {
        resourceNames =  
            Assembly.GetExecutingAssembly().GetManifestResourceNames(); 
    }

    return resourceNames.Contains(resourceName);
}
