推荐答案

在.NET中没有日期这样的东西。但是，有一个函数 Date ，它返回与参数相同的时间，当天的时间只是截断到午夜的12:00:00：

我相信你不需要它。您唯一的问题是您尝试仅在屏幕上显示日期，但也会显示时间。您只需要学习一般的格式，对于这种类型：

就是这样。

There is no such thing as just date in .NET. However, there is a function Date which returns the same time as argument, with time of the day simply "truncated" to 12:00:00 midnight:
http://msdn.microsoft.com/en-us/library/system.datetime.date.aspx[^].

I believe you don''t need it. Your only problem is that you try to show only the date on screen, but the time is also shown. You just need to learn formatting in general, and for this type:
http://msdn.microsoft.com/en-us/library/ht77y576.aspx[^],
http://msdn.microsoft.com/en-us/library/zdtaw1bw.aspx[^],
http://msdn.microsoft.com/en-us/library/8tfzyc64.aspx[^],
http://msdn.microsoft.com/en-us/library/az4se3k1.aspx[^],
http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx[^].

That''s it.

<div class="right" style="width: 166px; height: 19px;">
                                        <%# Eval("EvaluationDate", "{0:M-dd-yyyy}")%></div>

i在我的网格视图中使用它来解决它

i solve it using this in my grid view

protected void BindData()
        {
            string strFirstName = "";
            string strLastName="";
            DateTime? dtStartDate = null;
            DateTime? dtEndDate = null;
            var PatientEvaluations = objPatient.GetAllPatientEvaluation(strFirstName,strLastName,dtStartDate.ToString("dd/MM/yyyy"),dtEndDate.ToString("dd/MM/yyyy")).AsQueryable();

            GridViewPatient.DataSource = PatientEvaluations;
            GridViewPatient.DataBind();
        }

你试试这个，希望它能给你想要的结果。

You try this, hope it will give expected result what you needed.
