     EnableButtons(); 

     //Process face image 

     if (myUtil.ProcessFaceImage(imgFace)) 
     { 
      //Get positions from face image 
      lbLeftEyeXPos.Text = myUtil.GrFaceImage.LeftEye.X.ToString(); 
      lbLeftEyeYPos.Text = myUtil.GrFaceImage.LeftEye.Y.ToString(); 
      lbRightEyeXPos.Text = myUtil.GrFaceImage.RightEye.X.ToString(); 
      lbRightEyeYPos.Text = myUtil.GrFaceImage.RightEye.Y.ToString(); 
      lbMouthXPos.Text = myUtil.GrFaceImage.Mouth.X.ToString(); 
      lbMouthYPos.Text = myUtil.GrFaceImage.Mouth.Y.ToString(); 

     } 

    } 

    //Print the DLL version 
    private void mnVersion_Click(Object sender, EventArgs e) 
    { 
     myUtil.MessageVersion(); 
    } 


} 
} 

如果需要的話我可以張貼vb.net版本。

編輯：我已經添加了refference（System.Windows.Forms.dll）項目和所有其他我使用。

Answer 1

ListBox在裝配System.Windows.Forms.dll中被定義。確保你有一個參考該組件。

另外，你可能想

using System.Windows.Forms; 

Answer 2

使用System.Windows.Forms命名空間。要使用System.Windows.Forms命名空間，您必須添加System.Windows.Forms.dll作爲參考。

要添加引用，請按照下列步驟：

在Solution Explorer中，在項目節點上單擊鼠標右鍵，單擊添加引用。

在添加引用對話框中，選擇.NET選項卡並選擇System.Windows.Forms，然後單擊確定。

Answer 3

ListBox和PictureBox控件都可以在System.Windows.Forms命名空間中找到。將以下語句添加到您的代碼的頂部：

using System.Windows.Forms;

然後，參照System.Windows.Forms.dll
