你好，
我正在使用C#，
.aspx的代码
< asp:GridView ID ="GridView1" runat ="server" AutoGenerateColumns ="False" DataKeyNames ="id"
OnPageIndexChanging ="GridView1_PageIndexChanging"
OnRowCommand ="GridView1_RowCommand" PageSize ="10"
class ="table table-striped table-bordered datatables"
AllowPaging ="True">

</SelectParameters>
< asp:TemplateField>

< pagersettings mode ="NextPreviousFirstLast" pagebuttoncount ="4" previouspagetext =上一页">
NextPageText ="Next" FirstPageText ="First" LastPageText ="Last"/>
.cs
受保护的void GridView1_RowCommand(对象发送者，GridViewCommandEventArgs e)
{
如果(e.CommandName =="AddNew")
{
GridViewRow row =(GridViewRow)(((ImageButton)e.CommandSource).NamingContainer;
字符串curdate =(row.FindControl("txtdate")as TextBox).Text;
}
在curdate字符串中，我得到的输出是''2014/07/29''，我也想从我的currate字符串输出中获得月份，例如''07'' .

您可以简单地使用string.SubString-这是微不足道的-但不要.
取而代之的是，使用DateTime.TryParse和用户区域性解析日期输入，以获取DateTime，并从中获取月份.
You could simply use string.SubString - that''s trivial - but don''t.
Instead, parse the date input using DateTime.TryParse and the user culture to get a DateTime, and get the month from that.
首先阅读Sergey Alexandrovich Kryukov的解决方案(解决方案2)，然后如果您仍然选择弦乐而不是尝试我的解决方案.. :)
First read solution of Sergey Alexandrovich Kryukov (Solution 2) and than if you still go woth string than try my solution.. :)
string curdate = "29/07/2014";
string Month = curdate.Split('/')[1].ToString();
