[英]Using reflection copy object properties to another object
HI, HI,
I have code below but getting error "object does not match target type" on the prop.SetValue statement. 我有下面的代码,但在prop.SetValue语句中得到错误“对象与目标类型不匹配”。 But the types are both Int32.
但类型都是Int32。
private UniqueProjectType CreateUniqueProjectType(TBR.Domain.Project project)
{
UniqueProjectType type = new UniqueProjectType();
foreach (PropertyInfo prop in type.GetType().GetProperties())
{
if (prop.Name == "ID")
{}
else if (prop.Name == "PayFrequency")
type.PayFrequency = _tbrService.GetEmployee((int)project.EmployeeID).PayFrequency;
else
prop.SetValue(type, prop.GetValue(project, null), null);
}
return type;
}
I think here's the catch: 我认为这是一个问题:
prop.GetValue(project, null);
prop is specific to UniqueProjectType
while project
is TBR.Domain.Project
type. prop特定于
UniqueProjectType
而project
是TBR.Domain.Project
类型。 I think you should get all properties of TBR.Domain.Project
and find one that has corresponding name. 我想你应该获得
TBR.Domain.Project
所有属性,并找到一个具有相应名称的属性。
I think you should call GetValue on the PropertyInfo corresponding to the Project type. 我认为你应该在与Project类型对应的PropertyInfo上调用GetValue。 PropertyInfo instances are tied to a specific type.
PropertyInfo实例绑定到特定类型。
Basically, for each property info of the UniqueProjectType type, you have to look for a PropertyInfo on the Project type with the same name. 基本上,对于UniqueProjectType类型的每个属性信息,您必须在Project类型上查找具有相同名称的PropertyInfo。 Then you call GetValue and SetValue for the two objects using their corresponding PropertyInfo.
然后使用相应的PropertyInfo为两个对象调用GetValue和SetValue。
