BindingFlags.IgnoreCase not working for Type.GetProperty()?
提问by Boris Callens
Imagine the following
想象以下
A type T has a field Company. When executing the following method it works perfectly:
类型 T 有一个字段 Company。执行以下方法时，它完美地工作：
Type t = typeof(T);
t.GetProperty("Company")
Whith the following call I get null though
虽然下面的电话我得到了空值
Type t = typeof(T);
t.GetProperty("company", BindingFlags.IgnoreCase)
Anybody got an idea?
有人有想法吗？

You've overwritten the default look-up flags, if you specify new flags you need to provide all the info so that the property can be found. For example: BindingFlags.IgnoreCase | BindingFlags.Public | BindingFlags.Instance
您已经覆盖了默认查找标志，如果您指定新标志，您需要提供所有信息以便可以找到该属性。例如：BindingFlags.IgnoreCase | BindingFlags.Public | BindingFlags.Instance

You need to add BindingFlags.Public | BindingFlags.Instance
你需要添加 BindingFlags.Public | BindingFlags.Instance

Thanks, this really helped me out in a pinch today. I had audit information saved, but with incorrect casing on the property names. (The auditing is built into a datalayer.) Anyway so I had to add IgnoreCase as a binding flag, but then it still didn't work, till my coworker found this answer. The resulting function:
谢谢，这真的帮助了我今天的紧要关头。我保存了审计信息，但属性名称的大小写不正确。（审计内置在数据层中。）无论如何，我不得不添加 IgnoreCase 作为绑定标志，但它仍然不起作用，直到我的同事找到了这个答案。结果函数：
public static void SetProperty(Object R, string propertyName, object value)
{
Type type = R.GetType();
object result;
result = type.InvokeMember(
propertyName,
BindingFlags.SetProperty |
BindingFlags.IgnoreCase |
BindingFlags.Public |
BindingFlags.Instance,
null,
R,
new object[] { value });
}
This is part of a class I call DotMagic.
