对象与SetValue中的目标类型Exception不匹配

Question

//try to set this property .

 public List<USER_ROLE> list {get;set;}

var result = new List<USER_ROLE>() { new USER_ROLE()
                              { userid = 0,role_id = 1,role_cde = "00001"
                               }};
    //Get property with name of property.

object obj = Activator.CreateInstance(property.PropertyType);
var getva = property.GetValue(obj,null);// Object does not match target type


property.PropertyType.GetMethod("Add").Invoke(obj,new object[] { result });
if (obj.GetType() == property.PropertyType)
{
property.SetValue(obj, property, null);// object does not match target type.
}

运行时execption：对象与目标类型不匹配。我不明白目标类型，请告诉我哪里错了？

Answer 1

在查看the documentation后，似乎您认为第一个参数是原始对象，第二个参数是您要将属性设置为的值。

看起来你想将属性设置为obj，在这种情况下，你要做

property.SetValue(/*instance of whatever class has the property*/, obj, null);
