格式化时间为什么出错呢？public ...

public string Gettime( DateTime time)
<br>    {
<br>
<br>           return Convert.ToDateTime(time).ToShortDateString();
<br>       // return DateTime.Now.ToShortDateString().ToString();
<br>
<br>
<br>    }
<br>
<br>
<br>调用是               &lt;aspabel ID="JoinTime" runat="server" Text=&lt;%# Gettime(Eval("JoinTime")) %&gt;&gt;&lt;/aspabel&gt;
<br>怎么会出现
<br>
