错误:字符串未被识别为有效的DateTime. [英] Error: String was not recognized as a valid DateTime.

问题描述

我在项目中使用ajax日历扩展程序和文本框.将文本框值转换为日期时间格式时出现错误:"String was not recognized as a valid DateTime."
我正在使用以下代码:

I''m using an ajax calendar extender and a text box in my project. While converting the textbox value to the datetime format error is coming : "String was not recognized as a valid DateTime."
I''m using the following code:

<tr><td>
        <asp:CalendarExtender ID="CalendarExtender1" TargetControlID="txtfrom" runat="server" />
        </td><td><asp:TextBox ID="txtfrom" runat="server" CssClass="txtbx"></td></tr>

DateTime dt1 = Convert.ToDateTime(txtfrom.Text);

如何获取日期格式的texbox值?

谢谢.

How can I get the texbox value in date format?

Thank you.

我已将格式"属性更改为

< asp:calendarextender id ="CalendarExtender1" targetcontrolid ="txtfrom" runat ="server" format ="dd/MM/yyyy" xmlns:asp =#unknown">

现在工作正常.

谢谢.

I''ve changed the property ''Format'' as

<asp:calendarextender id="CalendarExtender1" targetcontrolid="txtfrom" runat="server" format="dd/MM/yyyy" xmlns:asp="#unknown">

and now it is working fine.

Thank you.

使用

Use

DateTime dt1 = DateTime.ParseExact(txtFrm.Text, "dd-MM-YYYY", null);

然后就可以了:-)
最好的:-)

Then it Works Fine :-)
All the Best :-)
