GetProperty适用于.NET 3.5,但不适用于.NET 4

Question

我使用以下代码:

protected object GetProperty(object target, string fieldName)
{
    Type type = target.GetType();
    PropertyInfo mi = type.GetProperty(
        fieldName, BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.GetProperty);
    object obj = mi.GetValue(target, null);
    return obj;
}

它适用于.NET 3.5.但如果我改为.NET 4,则mi变为null.为什么？

Answer 1

Does the target still have the desired property in .net 4? There were quite a few API Changes.
