如何解决错误“字符串未被识别为Vb.net有效日期时间”

我后面的代码如下：我想进入的日期为每对TextBox4前显示结束如何解决错误“字符串未被识别为Vb.net有效日期时间”

Protected Sub btnSave_Click1(ByVal sender As Object, ByVal e As EventArgs) Handles Button2.Click 

    Dim dt2 As OleDbParameter 
    dt2 = cmd.CreateParameter 
    dt2.OleDbType = OleDbType.Date 
    Dim dt As String = TextBox4.InnerText 
    dt2.Value = DateTime.ParseExact(dt,"M/dd/yyyy", Nothing) 
    dt2.ParameterName = "@StartDate" 
    cmd.Parameters.Add(dt2) 

End Sub

在我的ASPX前端代码如下

<div class="container" id="TextBox4" runat="server" width="181px" bordercolor="Black" borderstyle="Solid"> 
     <div class="row"> 
      <div class='col-sm-6'> 
      <div class="form-group"> 
       <div class='input-group date' id='datetimepicker1'> 
       <input type='text' class="form-control" /> 
       <span class="input-group-addon"> 
          <span class="glyphicon glyphicon-calendar"></span> 
       </span> 
       </div> 
      </div> 
      </div> 
      <script type="text/javascript"> 
       $(function() { 
        $('#datetimepicker1').datetimepicker(); 
       }); 
      </script> 
     </div> 
     </div>

[String未被识别为有效的DateTime异常。]（https://stackoverflow.com/questions/44031297/string-was-not-recognized-as-a-valid-datetime-exception） – VDWWD

@VDWWD感谢您的链接我试图从MM更改格式为M仍然拍摄错误 – Snb93

什么输入失败？ –

Protected Sub btnSave_Click1(ByVal sender As Object, ByVal e As EventArgs) Handles Button2.Click 

Dim dt2 As OleDbParameter 
dt2 = cmd.CreateParameter 
dt2.OleDbType = OleDbType.Date 
dt2.Value = = TextBox4.Text 
dt2.ParameterName = "@StartDate" 
cmd.Parameters.Add(dt2)

End Sub

这样编辑，它的作品感谢大家的反馈和帮助。
