如何在计算的日子里删除小时的小时数...... asp.net，C＃

问题描述

我是通过后面的代码创建一个Gridview表，

在Gridview表中，一列是从两个日期之间计算的天数，

对于列格式我在RowDataBound编写代码，

所以Days列格式没有转换，

显示Days.HH MM SS FFF也



请愿。任何人帮助我..



我尝试过：

  protected   void  Page_Load（对象发​​件人，EventArgs e）
 {
  //   Gridview数据绑定 
 DataClassesDataContext db =  new  DataClassesDataContext（）; 
  var  sumo = 来自 i   db.Chech_ins 
  let  Dys = DateTime.Now  -  i.IN_Date 
  select   new  
 {Gues_Name = i.Room_num，
 IN_Date = i.IN_Date，
 Today_Date = DateTime.Now，
天= Dys，
总计= i.Tariff *  2 ，
}; 
 GridView1.DataSource = sumo; 
 GridView1.DataBind（）; 
 
} 
 
 
 
 受保护  void  GridView1_RowDataBound（ object  sender，GridViewRowEventArgs e）
 {
 
  //  用于更改列格式 
  if （e.Row.RowType == DataControlRowType.DataRow）
 {
 
 e.Row.Cells [ 1 ]。Text = Convert.ToDateTime（e。 Row.Cells [ 1 ]。文本）.ToString（  DD-MM-YYYY）; 
 e.Row.Cells [ 2 ]。Text = Convert.ToDateTime（e.Row.Cells [ 2 ]。文本）.ToString（  dd-MM-yyyy）; 
 e.Row.Cells [ 3 ]。Text =  double  .Parse（e.Row .Cells [ 3 ]。Text）.ToString（）; 
 e.Row.Cells [ 4 ]。Text = Convert.ToInt32（e.Row.Cells [ 4 ]文本）的ToString（）; 
} 
} 

解决方案

I am was create one Gridview table through code behind,
In the Gridview table one column is for days counting from between two dates,
For the columns formate i wrote code in RowDataBound,
so in that Days column format is not converting,
It was showing Days.HH MM SS FFF also

pls. any one help me ..

What I have tried:

protected void Page_Load(object sender, EventArgs e)
    {
       // Gridview Data binding 
        DataClassesDataContext db = new DataClassesDataContext();
          var sumo = from i in db.Chech_ins
                     let Dys = DateTime.Now - i.IN_Date
                     select new
                   {   Gues_Name = i.Room_num,
                       IN_Date= i.IN_Date, 
                       Today_Date=DateTime.Now,
                       Days = Dys,
                       Total = i.Tariff * 2,
                   };
        GridView1.DataSource = sumo;
        GridView1.DataBind();
    
    }



protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {

       // for change the column formate
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
    
            e.Row.Cells[1].Text = Convert.ToDateTime(e.Row.Cells[1].Text).ToString("dd-MM-yyyy");
            e.Row.Cells[2].Text = Convert.ToDateTime(e.Row.Cells[2].Text).ToString("dd-MM-yyyy");
            e.Row.Cells[3].Text = double.Parse(e.Row.Cells[3].Text).ToString();
            e.Row.Cells[4].Text = Convert.ToInt32(e.Row.Cells[4].Text).ToString();
        }
    }
