C# 如何使用C实现SAP GUI 750的自动化#

问题：如何打开新的SAP GUI应用程序，以SAP登录而不是SAP轻松访问为目标

我知道这似乎是一个重复的问题，但它更多的是一个补充问题。由于我缺乏声誉积分，我无法在评论部分提问，因此请原谅我

我能够使用C成功地实现到SAP的连接，但是，它连接到的是“SAP轻松访问”，而不是“SAP登录”——一个更具视觉吸引力的GUI。我不一定关心视觉外观；问题在于某些按钮或文本输入字段不可用或不可见。 这是一张照片：

我认为问题在于DLL库或我不知道如何启动SAP登录实例并将其附加到会话

以下是我的代码，不包括敏感数据：

using System;
using SAPFEWSELib;

namespace RS_PostSettlementDataPull
{
    //SAPActive class to perform script operations
    public class SAPActive
    {
        //Class Member accessors
        public static GuiApplication SapGuiApp { get; set; }
        public static GuiConnection SapConnection { get; set; }
        public static GuiSession SapSession { get; set; }

    /**
     * Takes in a connection string and creates a GuiApplication linking
     * the SAP Connection and Session.
     *
     * Accepts DEFAULT connection.
     */
    public static void OpenSap(string env)
    {
        SAPActive.SapGuiApp = new GuiApplication(); //Need a way to explicitly create SAP Logon app

        string connectString = null;
        if (env.ToUpper().Equals("DEFAULT"))
        {
            connectString = "1.0 Test ERP (DEFAULT)";
        }
        else
        {
            connectString = env;
        }
        SAPActive.SapConnection = SAPActive.SapGuiApp.OpenConnection(connectString, Sync: true); //creates connection
        SAPActive.SapSession = (GuiSession)SAPActive.SapConnection.Sessions.Item(0); //creates the Gui session off the connection you made
    }

    /**

        client.SetFocus();

感谢您提供的任何帮助

我也有同样的问题。我不知道SAP是否像你写的那样连接到“SAP轻松访问”

我通过改变对象的类别来解决它：

sapEngine = new GuiApplication();
sapConnexion = sapEngine.OpenConnection(sapGUIConfig.EndPoint,Sync:true);
sapSession = (GuiSession)sapConnexion.Sessions.Item(0);

但是它可以像我在中发现的那样对您的scipt产生一些影响。

非常感谢您的回复。最后，我将所有涉及SAP脚本的流程都转移到python上。有一个模块模仿SAP的VB脚本，使事情变得更简单、更高效。干杯

sapROTWrapper = new SapROTWr.CSapROTWrapper();
sapGUIROT = _sapROTWrapper.GetROTEntry("SAPGUI");
//Get the reference to the Scripting Engine
sapEngine = sapGUIROT.GetType().InvokeMember("GetScriptingEngine", System.Reflection.BindingFlags.InvokeMethod, null, sapGUIROT, null);

sapConnexion = sapEngine.OpenConnection(sapGUIConfig.EndPoint);
sapSession = sapConnexion.Children(0);
