C#使用 SAPscript的方法

主要參照文檔 
https://wenku.baidu.com/view/a28b71adcf22bcd126fff705cc17552707225ed2.html?_wkts_=1693296465595&bdQuery=AxSAPFEWSELib.AxGuiApplication.GetScriptingEngine

裏面講得很清楚，但是那個文檔中，最大的問題是代碼不能Copy，而且
1)首先必須安裝SAP GUI,當然SAP服務器，賬號，密碼這些基本條件沒問題，還有就是賬號開放了SAP Script功能
2)程序參考中必須引用2個com組件  SAP GUI Scripting API/ SAPRotWr 1.0 Type Library （找不到說明SAP GUI沒有正確安裝)
3)加using SAPFEWSELib;using SapROTWr;
4）登陸部分的代碼

 
        private static object _lockObj = new object();
        public GuiConnection Connection { get; set; }
        public GuiSession Session { get; set; }


        internal GuiApplication GetGuiSAPApp(int timeOut = 10)
        {
            CSapROTWrapper sapROTWrapper = new CSapROTWrapper();
            return GetSAPGuiApp(sapROTWrapper, 10);
            
        }
        private GuiApplication GetSAPGuiApp(CSapROTWrapper sapROTWrapper,int secondsOfTimeOut)
        {
            object SapGuiRot = sapROTWrapper.GetROTEntry("SAPGUI");
            if (secondsOfTimeOut < 0)
            {
                throw new TimeoutException("獲取SAPGUI Application超時時間不能小於0。");
            }
            else
            {
                if (SapGuiRot == null)
                {
                    System.Threading.Thread.Sleep(1000);
                    return GetSAPGuiApp(sapROTWrapper, secondsOfTimeOut - 1);
                }
                else
                {
                    object engine = SapGuiRot.GetType().InvokeMember("GetSCriptingEngine", System.Reflection.BindingFlags.InvokeMethod, null, SapGuiRot, null);
                    if (engine == null)
                    {
                        throw new NullReferenceException("SAPGUI Application沒有發現。");
                    }
                    return engine as GuiApplication;
                }
            }
        }
        public void OpenConnection(string server)
        {
            lock (_lockObj)
            {
                var Application = GetGuiSAPApp(10);
                try
                {
                    Application.OpenConnectionByConnectionString(server);
                }
                catch(Exception ex)
                {
                    throw new Exception("連接異常，查看端口或者Host是否正確。"+ex.Message);
                }
                var index = Application.Connections.Count - 1;
                Connection = Application.Children.ElementAt(index) as GuiConnection;
                index = Connection.Sessions.Count - 1;
                if (Connection.Sessions.Count == 0)
                {
                    throw new Exception("新會話沒有發現，SAP客戶端是否開啓了腳本？");
                }
                Session = Connection.Children.Item(index) as GuiSession;
            }
        }

        public bool Login(string UserName,string Password,string Client,string Language = "")
        {
            (Session.FindById("wnd[0]/usr/txtRSYST-BNAME") as GuiTextField).Text = UserName;
            (Session.FindById("wnd[0]/usr/pwdRSYST-BCODE") as GuiTextField).Text = Password;
            (Session.FindById("wnd[0]") as GuiFrameWindow).SendVKey(0);
            return true;
        }

　5)實際使用

　　　　OpenConnection("server");  //server爲SAP地址或者服務器名
　　　　Login("usreName", "Password", ""); //用戶名和密碼

 

6）其它部分可以參照login裏面的進行修改.
