c# - Get Method in C#

Question

I came across C# codes in the following pattern but quite don't get where that Set method comes from.

// obj is an instance of Microsoft's Xrm Entity class
obj.Set("property_name", property_value);

Based on Xrm's Entity class definition, there is no member method called Set.

Can someone give me some light on this?

Answer 1

由于 C# 3.0 类可以获得未在类本身中声明的扩展方法。

我怀疑这里就是这种情况。

如果您在 Visual Studio 中，您可以右键单击Set呼叫并单击“转到定义”

您至少可以获得您正在使用的任何类的几乎任何成员的元数据文件。
