我写了个winform的用户控件，里面调用了用企业库写的dal方法，比如getNamebyId之类的，然后编后后拖入其他winform窗口里面报错，怎么回事？<br>
<br>
<br>
using System;<br>
using System.Collections.Generic;<br>
using System.ComponentModel;<br>
using System.Drawing;<br>
using System.Data;<br>
using System.Text;<br>
using System.Windows.Forms;<br>
using Haoting.DAL;<br>
using Haoting.BLL;<br>
<br>
namespace Haoting.UI<br>
{<br>
public partial class UserControl1 : UserControl<br>
{<br>
public UserControl1()<br>
{<br>
InitializeComponent();<br>
ProjectManager pm = new ProjectManager();<br>
label1.Text = pm.GetById("{8676E22F-1B62-4760-BF33-B8D44D4BB634}").Tables[0].Rows[0][0].ToString();<br>
}<br>
}<br>
}<br>
报错的图：<br>

请试一下下面的代码,如果还不行,请看一下这里:
http://www.cnblogs.com/deerchao/archive/2007/11/06/950675.html
namespace Haoting.UI
{
public partial class UserControl1 : UserControl
{
public UserControl1()
{
InitializeComponent();
if(!DesignMode)
{
ProjectManager pm = new ProjectManager();
label1.Text = pm.GetById("{8676E22F-1B62-4760-BF33-B8D44D4BB634}").Tables[0].Rows[0][0].ToString();
}
}
}
}
