获取对象类型并相应地分配值 [英] get object type and assign values accordingly

问题描述

我有一个数组列表，其中包含不同类型的值，第一个值-> 字符串，第二个值-> 日期时间，第三个值-> 布尔值，第4个值是 int ，如何找到自己的类型并相应地分配这些值，我们将为您提供帮助：）

I have an arraylist that gets different type of values in it, 1st value->string,2nd value-> datetime, 3rd value--> boolean and 4th value is int, how do I find thier type and assign those values accordingly, any help is appreciated:)

这是我的代码：

foreach (object obj in lstTop)
            {

              if(obj.GetType() == string)
                {do this...)
              else if(obj.GetType() == DateTime)
                {do this....}
              else if(obj.GetType() == bool)
                {do this....}
              else if(obj.GetType() == Int)
                {do this....}
            }

谢谢大家，我的最终代码：

string Subscription = "";
        DateTime issueFirst;
        DateTime issueEnd;

        foreach (object obj in lstTop)
        {
            ///Type t = obj.GetType();
            if (obj is string)
                Subscription += obj + ",";
            else if (obj is DateTime)
            {
               Subscription += Convert.ToDateTime(obj).ToShortDateString() + ",";
            }
           /// else if (t == typeof(DateTime))                
        }
    return ("User Authenticated user name: " + userName + ", Subscription: " + Subscription);

推荐答案

foreach (object obj in lstTop)
        {

          if(obj is string)
            {do this.....}
          else if(obj is DateTime)
            {do this.....}
          else if(obj is bool)
            {do this.....}
          else if(obj is Int)
            {do this.....}
          else
          {
              // always have an else in case it falls through
              throw new Exception();
          }
        }
