对象之间通过反射拷贝数据

/// <summary> /// Copies the data of one object to another. The target object 'pulls' properties of the first. /// This any matching properties are written to the target. /// /// The object copy is a shallow copy only.

下面两个参数跟据英文知道,

excludedProperties 这个参数可以是"属性1,属性2,属性3" 这样以逗号分隔的字符串
BindingFlags 
就是枚举罗 

BindingFlags bf = BindingFlags.Public | BindingFlags.Static...... 

string 
excludedProperties, BindingFlags 
memberAccess
