C#反射动态赋值

很多时候我们需要在数据实体层读取数据后赋值到领域模型时往往会产生如下的代码

1publicclassA2{3publicstringName {get;set;}4publicintAge {get;set;}5}67publicclassB8{9publicstringName {get;set;}10publicintAge {get;set;}11}1213staticvoidmain(string[] args)14{15A a=newA();16a.Name ="aa";17a.Age =1;18B b =newB();19b.Name =a.Name;20b.Age =a.Age;21}2223

这样的话会产生很多工作量，我们可以使用反射动态为对象赋值，只要属性名一直就可以。

1publicstaticclassCommon2{3publicstaticvoidCopyTo<T>(thisobjectsource, T target)4whereT :class,new()5{6if(source ==null)7return;89if(target ==null)10{11target =newT();12}1314foreach(varPRopertyintarget.GetType().GetProperties())15{16varpropertyValue = source.GetType().GetProperty(property.Name).GetValue(source,null);17if(propertyValue !=null)18{19if(propertyValue.GetType().IsClass)20{2122}23target.GetType().InvokeMember(property.Name, BindingFlags.SetProperty,null, target,newobject[] { propertyValue });24}2526}2728foreach(varfieldintarget.GetType().GetFields())29{30varfieldValue =source.GetType().GetField(field.Name).GetValue(source);31if(fieldValue !=null)32{33target.GetType().InvokeMember(field.Name, BindingFlags.SetField,null, target,newobject[] { fieldValue });34}35}36}37}

调用方式

staticvoidmain(string[] args)

{

A a=newA();

a.Name="aa";

a.Age=1;

B b=newB();

a.CopyTo(b);

}
