使用 Daynamic 动态添加属性

时间:2024-10-25 19:33:44

所谓的Dynamic 动态类型,页面也要是动态的(强撸)

很简单的 直接上代码:

//案例一

DynamicpersonCollection = new ObservableCollection();

for (var i = 0; i < 10; i++) {

dynamic p = new ExpandoObject();

((IDictionary<string, object>)p).Add("Name", "22");

((IDictionary<string, object>)p).Add("Age", "cc");

DynamicpersonCollection.Add(p);

}

//案例二

var DynamicpersonCollection = new ObservableCollection<dynamic>();
for (int i = 0; i < 2; i++)
{
string s = "你好";
dynamic p = new ExpandoObject();
p.aa = "ss";
((IDictionary<string, object>)p).Add("GroupName" + (i + 2).ToString(), s);
DynamicpersonCollection.Add(p);
}

案例三

public class NurseScheduleStatisticsModel : DynamicObject
{
public string EmpName { get; set; }
public string TotalHour { get; set; }
public string TotalWork { get; set; } Dictionary<string, object> Properties = new Dictionary<string, object>(); public override bool TrySetMember(SetMemberBinder binder, object value)
{
if (!Properties.Keys.Contains(binder.Name))
{
         //在此可以做一些小动作

          //if (binder.Name == "Col")
          //  Properties.Add(binder.Name + (Properties.Count), value.ToString());
          //else
          //  Properties.Add(binder.Name, value.ToString());

                Properties.Add(binder.Name, value.ToString());
}
return true;
}
public override bool TryGetMember(GetMemberBinder binder, out object result)
{
return Properties.TryGetValue(binder.Name, out result);
}
}
