c# - 将字符串与类属性名称匹配

Question

我有一个类，假设有 5 个属性

Int32 Property1;
Int32 Property2;
Int32 Property3;
Int32 Property4;
Int32 Property5;

现在我必须动态设置其中三个属性的值。到目前为止没问题，但我的问题是我在运行时将这三个属性名称作为字符串获取。让我们说，像这样的东西..

List<String> GetPropertiesListToBeSet()
{
   List<String> returnList = new List<String>();
   returnList.Add("Property1");
   returnList.Add("Property3");
   returnList.Add("Property4");
   retun returnList;
}

现在，

 List<String> valuesList = GetPropertiesToBeSet();

 foreach (String valueToSet in valuesList)
 {
 // How Do I match these Strings with the property Names to set values
    Property1 = 1;
    Property3 = 2;
    Property4 = 3;
 }

你可以这样做。属性是你的类

        Properties p = new Properties();
        Type tClass = p.GetType();
        PropertyInfo[] pClass = tClass.GetProperties();

        int value = 0; // or whatever value you want to set
        foreach (var property in pClass)
        {
            property.SetValue(p, value++, null);
        }
