尝试将UserControl添加到我的表单时出错

Question

我在添加UserControl到表单时遇到问题。

用户控件编码：

using System; 
using System.Windows.Forms; 

namespace Most.Mobile.AFV.UI.Controls 
{ 
    public partial class ListActionBar : UserControl 
    { 
     public ListActionBar() 
     { 
      InitializeComponent(); 
     } 

     public bool ShowKeyboardButton 
     { 
      get { return mtbKeyboard.Visible; } 
      set { mtbKeyboard.Visible = value; } 
     } 

     public bool ShowOpenButton 
     { 
      get { return mtbMenu.Visible; } 
      set { mtbMenu.Visible = value; } 
     } 

     public bool ShowDeleteButton 
     { 
      get { return mtbDelete.Visible; } 
      set { mtbDelete.Visible = value; } 
     } 

     public bool ShowBackButton 
     { 
      get { return mtbBack.Visible; } 
      set { mtbBack.Visible = value; } 
     } 

     public bool ShowEditButton 
     { 
      get { return mtbEdit.Visible; } 
      set { mtbEdit.Visible = value; } 
     } 

     public bool ShowNewButton 
     { 
      get { return mtbNew.Visible; } 
      set { mtbNew.Visible = value; } 
     } 

     public event EventHandler NewClick; 
     public event EventHandler DeleteClick; 
     public event EventHandler EditClick; 
     public event EventHandler OpenClick; 

     private void mtbBack_Click(object sender, EventArgs e) 
     { 
      if (Parent == null) 
       return; 

      if (Parent is Form) 
       (Parent as Form).DialogResult = DialogResult.Cancel; 
     } 

     private void mtbKeyboard_Click(object sender, EventArgs e) 
     { 
      inp.Enabled = !inp.Enabled; 
     } 

     private void mtbNew_Click(object sender, EventArgs e) 
     { 
      if (NewClick != null) 
       NewClick(sender, e); 
     } 

     private void mtbEdit_Click(object sender, EventArgs e) 
     { 
      if (EditClick != null) 
       EditClick(sender, e); 
     } 

     private void mtbDelete_Click(object sender, EventArgs e) 
     { 
      if (DeleteClick != null) 
       DeleteClick(sender, e); 
     } 

     private void mtbMenu_Click(object sender, EventArgs e) 
     { 
      if (OpenClick != null) 
       OpenClick(sender, e); 
     } 
    } 
} 

下面对错误的图象

错误说明：

无法创建部件 '' “System.IO.FileLoadException：无法加载文件或程序集'Microsoft.WindowsCE.Forms，Version = 3.5.0.0，CUlture = neutral，PublicKeyToken = 9 69db8053d3322ac'或其依赖项之一。

在设计器视图中显示控件时，visual studio designer会实例化控件。当你得到这样的错误时，通常意味着你有一个运行时错误。如果它编译，请尝试运行代码（不要在设计器中打开它）并查看它在哪里/是否崩溃。
