解决方案

嗨!!!你喜欢这样!!!



<前lang =c＃> 受保护 void btn_Click（ object sender，EventArgs e）
{
// 在这里你使用你的ddl，combobox等插入年龄日期
DateTime dtStart = DateTime.Parse（txtDoB.Text ）;
TimeSpan sp = DateTime.Now - dtStart;
int year = 18;
int days = 365 ;
int total = year * days;

if （sp.Days < total）
{

txtDoB.Text = 无效;
lblMess.Text = 你不能低于18岁;
lblMess.CssClass = Errr;
return ;
}
}

它唯一的基本想法是怎么做!!!!你在VB.net中使用c＃中的代码我认为它应该可以帮助你!!!!!!

 受保护  Sub  btn_Click（发件人作为 对象，e  As  EventArgs）
 ' 在这里使用插入年龄日期的ddl，combobox等 
  Dim  dtStart  As  DateTime = DateTime.Parse（txtDoB.Text）
  Dim  sp  As  TimeSpan = DateTime.Now  -  dtStart 
  Dim  year  As  整数 =   18 
 昏暗天作为 整数 =  365  
  Dim  total  As  整数 =年*天
 
 如果 sp.Days<总计然后 
 
 txtDoB.Text =  无效 
 lblMess.Text =  您不能低于18岁 
 返回 
 结束 如果 
 结束  Sub  

< br $> b $ b

希望我帮助你。

试试这个：

  Dim  strDOB  As   String  
 strDOB = txtDateOfBirth.TextDim 
 intAge  As   Integer  
 intAge = Math.Floor（ DateDiff（DateInterval.Month，DateValue（strDOB），Now（））/  12 ）
 lblAge.Text = intAge

Hi!!! you do like that!!!

protected void btn_Click(object sender, EventArgs e)
    {
         // here you use your ddl,combobox or etc where age date is inserted
        DateTime dtStart = DateTime.Parse(txtDoB.Text);
        TimeSpan sp = DateTime.Now - dtStart;
        int year = "18";
        int days = 365;
        int total = year * days;

        if (sp.Days < total)
        {

            txtDoB.Text = "Not Valid";
            lblMess.Text = "You can not be under 18 years";
            lblMess.CssClass = "Errr";
            return;
        }
}

its only basic idea of how to do !!!! have code in c# you do in VB.net i think it should help you!!!!!!

Protected Sub btn_Click(sender As Object, e As EventArgs)
    ' here you use your ddl,combobox or etc where age date is inserted
    Dim dtStart As DateTime = DateTime.Parse(txtDoB.Text)
    Dim sp As TimeSpan = DateTime.Now - dtStart
    Dim year As Integer = "18"
    Dim days As Integer = 365
    Dim total As Integer = year * days

    If sp.Days < total Then

        txtDoB.Text = "Not Valid"
        lblMess.Text = "You can not be under 18 years"
        Return
    End If
End Sub

Hope I help you.

Try this:

Dim strDOB As String
strDOB = txtDateOfBirth.TextDim 
intAge As Integer
intAge = Math.Floor(DateDiff(DateInterval.Month, DateValue(strDOB), Now()) / 12)
lblAge.Text = intAge
