如何检查财产设定者是否公开 [英] How to check if property setter is public

问题描述

给出一个PropertyInfo对象，如何检查该属性的设置程序是否公开？

Given a PropertyInfo object, how can I check that the setter of the property is public?

推荐答案

检查得到的内容从 GetSetMethod ：

Check what you get back from GetSetMethod:

MethodInfo setMethod = propInfo.GetSetMethod();

if (setMethod == null)
{
    // The setter doesn't exist or isn't public.
}

或者，对理查德的答案：

if (propInfo.CanWrite && propInfo.GetSetMethod(/*nonPublic*/ true).IsPublic)
{
    // The setter exists and is public.
}

请注意，如果您只想设置一个属性，有一个塞特犬，您实际上不必关心塞特犬是否是公开的。您可以使用它，公共或私有：

Note that if all you want to do is set a property as long as it has a setter, you don't actually have to care whether the setter is public. You can just use it, public or private:

// This will give you the setter, whatever its accessibility,
// assuming it exists.
MethodInfo setter = propInfo.GetSetMethod(/*nonPublic*/ true);

if (setter != null)
{
    // Just be aware that you're kind of being sneaky here.
    setter.Invoke(target, new object[] { value });
}
