GetCustomAttributes获取不到类型属性
有个项目需要调用别人C#工程的DLL，但是用GetCustomAttributes获取不到类型的属性。
下面的代码是别人C#工程中调用DLL的代码，可以正常获取到类型的属性。但是同样的代码放到我的C#工程中就不行了。接触C#还不到两周，还不熟悉。请帮忙分析一下什么情况会导致我的问题？谢谢啦
private bool LoadPlugin()
{
foreach (string fileName in Directory.GetFiles(_PluginPath.ToString()))
{
FileInfo file = new FileInfo(fileName);
if (!file.Extension.Equals(".dll")) continue;
Assembly pluginAssembly = Assembly.LoadFrom(fileName);
foreach (Type pluginType in pluginAssembly.GetTypes())
{
// Only look at public types and non-abstract types
if (!pluginType.IsPublic || pluginType.IsAbstract)
{
continue;
}
// Get a type object of the interface we need the plugins to match
Type typeInterface = pluginType.GetInterface("XXX.PlugIn.IPlugIn", true);
// Make sure the interface we want to use actually exists
if (typeInterface == null)
{
continue;
}
foreach (PlugInAttribute attribute in pluginType.GetCustomAttributes(typeof(PlugInAttribute), true))
{
if (null == attribute)
{
continue;
}
if (attribute.Application != "ABC")
{
continue;
}
IPlugIn Instance = (IPlugIn)Activator.CreateInstance(pluginAssembly.GetType(pluginType.ToString()));
typeInterface = null;
break;
}//foreach
typeInterface = null;
}//foreach
pluginAssembly = null;
}
return true;
}
