通过反射获取 MemberInfo 的类型

Getting the type of a MemberInfo with reflection(通过反射获取 MemberInfo 的类型)

问题描述

我正在使用反射来加载具有项目类结构的树视图.类中的每个成员都有一个分配给他们的自定义属性.

I'm using reflection to load a treeview with the class structure of a project. Each of the members in a class have a custom attribute assigned to them.

使用 MemberInfo.GetCustomAttributes() 获取类的属性没有问题，但是我需要一种方法来确定类成员是否是自定义类，然后需要对其自身进行解析返回自定义属性.

I don't have a problem getting the attributes for a class using MemberInfo.GetCustomAttributes() however I need a way of working out if a class member is a custom class and then needs parsing itself to return the custom attributes.

到目前为止，我的代码是:

So far, my code is:

MemberInfo[] membersInfo = typeof(Project).GetProperties();

foreach (MemberInfo memberInfo in membersInfo)
{
    foreach (object attribute in memberInfo.GetCustomAttributes(true))
    {
        // Get the custom attribute of the class and store on the treeview
        if (attribute is ReportAttribute)
        {
            if (((ReportAttribute)attribute).FriendlyName.Length > 0)
            {
               treeItem.Items.Add(new TreeViewItem() { Header = ((ReportAttribute)attribute).FriendlyName });
            }
        }
        // PROBLEM HERE : I need to work out if the object is a specific type
        //                and then use reflection to get the structure and attributes.
    }
}

是否有一种简单的方法可以获取 MemberInfo 实例的目标类型，以便我可以适当地处理它?我觉得我遗漏了一些明显的东西，但我现在正在绕圈子.

Is there an easy way of getting the target type of a MemberInfo instance so I can handle it appropriately? I feel I'm missing something obvious but I'm going round in circles at the minute.

推荐答案

GetProperties 返回一个 PropertyInfo 数组，所以你应该使用它.
那么使用 PropertyType 属性.

GetProperties returns an array of PropertyInfo so you should use that.
Then it is simply a matter of using the PropertyType property.

PropertyInfo[] propertyInfos = typeof(Project).GetProperties();

foreach (PropertyInfo propertyInfo in propertyInfos)
{
    // ...
    if(propertyInfo.PropertyType == typeof(MyCustomClass))
        // ...
}
