使用属性名称设置属性值

问题描述:


可能重复:

我可以使用Reflection设置属性值吗?

当仅具有属性的字符串名称时,如何使用反射设置类的静态属性?例如,我有:

How do I set a static property of a class using reflection when I only have its string name of the property? For instance I have:

List<KeyValuePair<string, object>> _lObjects = GetObjectsList();

foreach(KeyValuePair<string, object> _pair in _lObjects) 
{
  //class have this static property name stored in _pair.Key
  Class1.[_pair.Key] = (cast using typeof (_pair.Value))_pair.Value;
}

我不知道如何使用属性名称字符串。一切都是动态的。我可以使用列表中的5种不同类型的项来设置类的5个静态属性。

I don't know how I should set the value of the property using the property name string. Everything is dynamic. I could be setting 5 static properties of a class using 5 items in the list that each have different types.

感谢您的帮助。

答案:

Type _type = Type.GetType("Namespace.AnotherNamespace.ClassName");
PropertyInfo _propertyInfo = _type.GetProperty("Field1");
_propertyInfo.SetValue(_type, _newValue, null);


您可以尝试以下类似方法

You can try something like this

List<KeyValuePair<string, object>> _lObjects = GetObjectsList(); 
var class1 = new Class1();
var class1Type = typeof(class1); 
foreach(KeyValuePair<string, object> _pair in _lObjects)
  {   
       //class have this static property name stored in _pair.Key     
       class1Type.GetProperty(_pair.Key).SetValue(class1, _pair.Value); 
  }
