如何从propertydescriptor获取类名？ [英] How to get class name from propertydescriptor ?

问题描述

大家好，



我有属性描述符集合，但我无法获得与属性相关的类名。任何人都可以分享我如何从propertydescriptor获取类名，我必须得到该类的属性信息？



谢谢和问候，

Amal



我是什么尝试过：



为了获得propertyinfo我试过的propertyinfo.GetType（）。GetProperties（BindingFlags.Public | BindingFlags.Instance）



但是我无法获得确切的信息。当我尝试使用

类型t = TypeOf（ClassName）;

PropertyInfo propertyInfo = t.GetProperties（BindingFlags.Public | BindingFlags.Instance）;

i获得了所需的信息，但我必须在所需的位置提供类名。我必须动态获取classname以获取上面的propertyinfo。

解决方案

你可以试试

TypeDescriptor.GetClassName Method（Object，Boolean）（System.ComponentModel） [ ^ ]

使用ComponentType属性：

 SMThumbnailSet ts =  new  SMThumbnailSet（ @  D：\ Temp \ NoThumbs）; 
 PropertyDescriptorCollection pdc = TypeDescriptor.GetProperties（ts）; 
 PropertyDescriptor prop = pdc.Find（  MaxIndex，假）; 
类型t = prop.ComponentType; 
 Console.WriteLine（t.ToString（））; 

将打印：

 SMUtilityClasses.SMThumbnailSet 

Hi All,

I have property-descriptor collection , but i couldn't get the class name in which the properties are related. Could anyone share me how to get the class name from the propertydescriptor which i have to get the propertyinfo of that class?

Thanks and Regards,
Amal

What I have tried:

In order to get the propertyinfo i tried by propertyDescriptor.GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance)

but i could not get the exact information. When i try using the
Type t= TypeOf(ClassName);
PropertyInfo propertyInfo= t.GetProperties(BindingFlags.Public| BindingFlags.Instance);
i got the needed information, Yet i have to give the classname in the needed place. I have to get the classname dynamically here to get the propertyinfo as above.

解决方案

You could try
TypeDescriptor.GetClassName Method (Object, Boolean) (System.ComponentModel)[^]

Use the ComponentType property:

SMThumbnailSet ts = new SMThumbnailSet(@"D:\Temp\NoThumbs");
PropertyDescriptorCollection pdc = TypeDescriptor.GetProperties(ts);
PropertyDescriptor prop = pdc.Find("MaxIndex", false);
Type t = prop.ComponentType;
Console.WriteLine(t.ToString());

Will print:

SMUtilityClasses.SMThumbnailSet
