如何将VSTS编码的Ui脚本调用到QTP

我正试图在QTP上执行我的编码UI脚本。首先，我为我的编码UI项目创建了一个dll，后来我可以访问该dll中的方法，但我无法访问编码UI测试方法。示例：下面的脚本在VSTS 中的C#中

namespace TestProject1
{
    using System;
    using System.Collections.Generic;
    using System.Drawing;
    using System.Windows.Input;
    using System.Windows.Forms;
    using System.CodeDom.Compiler;
    using System.Text.RegularExpressions;
    using Microsoft.VisualStudio.TestTools.UITest.Extension;
    using Microsoft.VisualStudio.TestTools.UITesting;
    using Microsoft.VisualStudio.TestTools.UnitTesting;
    using Keyboard = Microsoft.VisualStudio.TestTools.UITesting.Keyboard;
    using Mouse = Microsoft.VisualStudio.TestTools.UITesting.Mouse;    
    using MouseButtons = System.Windows.Forms.MouseButtons;
    using Microsoft.VisualStudio.TestTools.UITesting.WinControls;
    using Microsoft.VisualStudio.TestTools.UITesting.HtmlControls;
    using Microsoft.VisualStudio.TestTools.UITesting.WpfControls;
    public partial class UIMap
    {
        public int MyInteger()
        {
            return 9;
        }
        public string testDll()
        {
            return "Test DLL Factory";
        }
        public void add1()
        {
            MessageBox.Show("Sravan");
        }
        public void DeletePhoto()
        {
            WinWindow window = new WinWindow();
            window.SearchProperties[WinWindow.PropertyNames.Name] = "Cyramed";
            window.SearchProperties.Add(new PropertyExpression(WinWindow.PropertyNames.ClassName, "WindowsForms10.Window", PropertyExpressionOperator.Contains));
            WinWindow c_window = new WinWindow(window);
            c_window.SearchProperties[WinWindow.PropertyNames.ControlName] = "PICTUREBOX1";
            c_window.WindowTitles.Add("Cyramed");
            c_window.DrawHighlight();
            WinClient c_client = new WinClient(c_window);
            c_client.WindowTitles.Add("Cyramed");
            c_client.DrawHighlight();
            Mouse.Click(c_client, MouseButtons.Right);
            Keyboard.SendKeys("{DOWN}");
            Keyboard.SendKeys("{DOWN}");
            Keyboard.SendKeys("{DOWN}");
            Keyboard.SendKeys("{ENTER}");

        }        
    }
}

我可以调用MyInteger和testDll方法，但当我调用DeletePhoto方法时，它会抛出一个错误："Could not load file or assembly 'Microsoft.VisualStudio.TestTools.UITesting, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified."

我主要关心的是：我也想在QTP上执行编码的UI脚本。
