step by step 教你用SAP NCO3.0调用RFC

需要的工具：

开发工具：Microsoft Visual Studio 2010 C#环境

NCO3.0：sapnco30dotnet40P_8-20007347.zip(VS2010环境下必须这个版本)

可到此下载：http://download.csdn.net/detail/easyboot/9457770

之后新建项目我这里新建的WPF

需要引用sapnco 和sapnco_utils

在代码中引用 SAP.Middleware.Connector

myfun.Invoke(dest);

IRfcStructure rfcReturn = myfun.GetStructure("RETURN"); //此处返回类型为Structure 如果是Single类型 则直接调用myfun.GetString("RETURN");

string s = rfcReturn.GetString("TYPE");

}

private void button1_Click(object sender, RoutedEventArgs e)

{

getSAPData();

}

}
