C# 用nco Call SapRfc函式

首先呼叫sap有兩種方式，一種是用VB或者VB.net ,新建VB類庫 並新增類
Functions類
Public Class Functions Implements IFunctions Private m_sapObject As Object 'sap遠端函式呼叫物件 Protected m_sapFun As Object 'sap函式 Private m_sapConnection As Object '與SAP的連線 ''' <summary> ''' 建構函式，傳入sap的基本資訊''' </summary> ''' <param name="sapSystem">Sap系統，可以傳入null</param> ''' <param name="applicationServer">SAP伺服器ip</param> ''' <param name="Client">集團號，如800</param> ''' <param name="SystemNumber">系統編號，如00</param> ''' <remarks></remarks>Public Sub New(ByVal sapSystem As String, ByVal ApplicationServer As String, ByVal Client As String, ByVal SystemNumber As String) Me.m_sapObject = CreateObject("SAP.Functions") Me.m_sapConnection = Me.m_sapObject.Connection() If String.IsNullOrEmpty(sapSystem) = False ThenMe.m_sapConnection.System = sapSystem End If Me.m_sapConnection.ApplicationServer = ApplicationServer Me.m_sapConnection.Client = Client Me.m_sapConnection.SystemNumber = SystemNumber End Sub ''' <summary> ''' 登入SAP，成功，返回True，失敗，返回False ''' </summary> ''' <param name="User">使用者</param> ''' <param name="PassWord">口令</param> ''' <param name="Language">語言，如ZH、EN等，可以傳入null</param> ''' <returns>是否登入成功</returns> ''' <remarks></remarks> Public Function ConnectToSAP(User As String, Password As String, Language As String) As Boolean Implements IFunctions.ConnectToSAP Me.m_sapConnection.user = User Me.m_sapConnection.Password = Password If String.IsNullOrEmpty(Language) = False Then Me.m_sapConnection.Language = Language Else Me.m_sapConnection.Language = "EN" End If Me.m_sapObject.AutoLogon = True '自動登入 Return Me.m_sapObject.Connection.logon(0, True) '登入是否成功 End Function ''' <summary> ''' 設定呼叫的sap函式名稱 ''' </summary> ''' <param name="sapFuncName">sap函式名稱</param> ''' <remarks></remarks> Public Sub SetFuncName(sapFuncName As String) Implements IFunctions.SetFuncName Me.m_sapFun = Me.m_sapObject.Add(sapFuncName) If m_sapFun Is Nothing Then Throw New Exception("Sap遠端函式名無效：" + sapFuncName) End If End Sub ''' <summary> ''' 設定Sap函式的傳入呼叫引數 ''' </summary> ''' <param name="paramName">引數名稱</param> ''' <param name="paramValue">引數值</param> ''' <remarks></remarks> Public Sub SetParamName(paramName As String, paramValue As Object) Implements IFunctions.SetParamName Dim param As Object param = Me.m_sapFun.Exports(paramName) If param Is Nothing Then Throw New Exception("Sap遠端函式的引數名無效：" + paramName) End If param.Value = paramValue End Sub ''' <summary> ''' 設定sap的傳入內表，用dt_value模擬這個內表 ''' </summary> ''' <param name="SapTableName">sap函式傳入內表的名字</param> ''' <param name="dt_value">模擬的DataTable，要求與傳入內表的欄位名一致</param> ''' <remarks></remarks> Public Sub SetInPutTable(SapTableName As String, dt_value As DataTable) Implements IFunctions.SetInPutTable Dim sapdata As Object 'sap傳入內表 Dim saprow As Object 'sap傳入內表的一行 Dim dc As DataColumn Dim index As Integer sapdata = Me.m_sapFun.Tables(SapTableName) For index = 0 To dt_value.Rows.Count -

C#引入類庫，並呼叫：
SapHelper sap = new SapHelper("127.0.0.1", "SFC_USER", "yhpwd", "801", "04", "EN"); SoDetailConn.SetFuncName("ZRFC_GET_SALES_DETAIL");//執行的RFC名稱 SoDetailConn.SetParamName("ORDERNUM", ""); SoDetailConn.SetParamName("PLANT", ""); SoDetailConn.ExecFun();//執行這個RFC DataTable outPutTable = SoDetailConn.GetOutPutTable("aa,bb", "table1", true);//返回的Table
專案右鍵引入rscp4n 、sapnco 、sapnco.utils三個引用
