c# - 简化从表单获取数据

Question

我填写了表格，并在服务器上收到了这样的数据:

model.Firstname = HttpContext.Current.Request.QueryString["Firstname"];
model.Lastname = HttpContext.Current.Request.QueryString["Lastname"];
model.Middlename = HttpContext.Current.Request.QueryString["Middlename"];
model.Avatar = HttpContext.Current.Request.QueryString["Avatar"];
model.Birthday = HttpContext.Current.Request.QueryString["Birthday"];

型号:

public int CustomerID { get; set; }
public int StatusID { get; set; }
public string Firstname { get; set; }
public string Lastname{ get; set; }
public string Middlename { get; set; }
public string Birthday { get; set; }

有没有什么办法可以更容易地合并这些行？

Answer 1

您可以编写一个扩展方法并使用反射来设置您的属性，如下所示:

public static void SetProperties<T>(this T source, HttpContext context)
{
     var properties = typeof(T)
             .GetProperties(BindingFlags.Instance | BindingFlags.Public);

     var  values = context.Request.QueryString;

     foreach (var prop in properties)
     {
         if (values.AllKeys.Contains(prop.Name))
         {
             prop.SetValue(source,values[prop.Name]);
         }
     }
}

用法:

mode.SetProperties(HttpContext.Current);

这假设查询字符串中的键与 model 的属性名称完全匹配。
