如何使用c#自动化SAP GUI

Question

我想使用C#语言自动化SAP GUI窗口.我能够在VBScript中完成它,但代码重用是可怕的.除了Id喜欢使用线程而不是运行80个或更多进程.我在哪里可以找到有关如何执行此操作的任何文档和示例？这是我正在使用的代码.基本上,我面临的问题是 - 如何建立与SAP GUI的连接,然后动态创建SAP GUI,然后开始进行交易并在某些字段中输入文本.

using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using White.Core.Factory;
using White.Core.UIItems.Finders;
using White.Core.InputDevices;
using System.Threading;
using System.Diagnostics;
using SAP.Connector;
using SAP;


namespace SAP_Automation
{
    class Program
    {
        public static void Main(string[] args)
        {
            string ExeSourceFile = @"C:\Program Files\SAP\SapSetup\setup\SAL\SapLogon.s8l";
            White.Core.Application _application;
            White.Core.UIItems.WindowItems.Window _mainWindow;

            var c = SAP.Connector.Connection.GetConnection("**");
            var c = new SAPConnection("ASHOST=*; GWHOST=*; GWSERV=*; ASHOST=*; SYSNR=00;USER=user; PASSWD=**;");
            c.Open();


            }
        }
    }
}

如您所见,我可以创建连接,但我不知道如何创建GUI的会话并开始在字段中输入文本.任何例子和样品将不胜感激.

Answer 1

这可能是坏死线程,但我处于类似的情况,我工作.我们需要SAP GUI Automation进行测试,以便与我们用C#编写的本土自动化平台的其他部分集成.我帮助创建了一个解决方案,该解决方案利用SAP提供的GUI自动化库,可以用作SAP自动化层的基础.

SAP文件安装中是否存在以下文件？x:\ Program Files\SAP\FrontEnd\SAPGui\sapfewse.ocx？

如果是这样,请将其添加到Visual Studio(或您正在使用的任何IDE)作为参考.它基本上是一个类库,其中包含一组允许您与之交互的SAP特定对象.它非常有效,因为它可以从SAP GUI中显示您需要的大部分内容.我们在其他尝试中发现SAP中的许多对象都不可用.

这是我做过的概念的早期证明.使用连接字符串启动SAP,输入凭据,导航到事务代码.

你是对的,没有很多关于这个主题的文件.以下是一些帮助我入门的资料

- 我们计划的原始来源 http://scn.sap.com/thread/1729689

- 关于API的文档(对于VB和javascript,但一般规则和对象是相同的).绝对阅读SAP GUI Runtime层次结构上的部分.它会回答很多问题. http://www.synactive.com/download/sap%20gui%20scripting/sap%20gui%20scripting%20api.pdf
