SapNwRfc中的配置参数，记录日志关闭 Trace=0，可以得到很好的性能。

有网友在问，SAP RFC返回多张表（C# 使用 SapNwRfc 一）中如何输入一张表的数据，正好博主也遇到了这个场景，今天做了一个DEMO，详细代码如下：

using SapNwRfc;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace saprfc2024table
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void toolStripButton1_Click(object sender, EventArgs e)
        {
            callsap();
        }

        void callsap()
        {
            string connectionString = "AppServerHost=xxx.xxx.xxx.xxx; SystemNumber=00; User=xxxxxx;Password=xxxxxxx Client=700; Language=ZH; PoolSize=5; Trace=0";
            var connection = new SapConnection(connectionString);
            connection.Connect();
            toolStripStatusLabel1.Text = "Logon SAP Server...";

        
            /*
            InputItem[] inputItem  = new InputItem[]
            {
                new InputItem { WERKS = "1003"  },
                new InputItem { WERKS = "1003"  },

            };
            */


            //新建一个对象数组，大小10000
            InputItem[] inputItem = new InputItem[10000];
            for (int i = 0; i < 10000; i++)
            {
                inputItem[i] = new InputItem { WERKS = "1003",ZMENG = i };
            }

            //对象数组交给对象表
            InputTable inputTable = new InputTable();
            inputTable.Items = inputItem;
            
            //调用函数，输入是一张表10000条数据，输出是函数返回的结果
            var someFunction = connection.CreateFunction("ZSAP_PP_APS_XXXXX_IN");
            var result = someFunction.Invoke<ReturnTable>(inputTable);
            

            //显示返回的结果
            foreach ( var item in result.Items ) 
            { 
                listBox1.Items.Add(item.STATUS + " " + item.MESSAGE);
            }
        }
    }


    class InputTable 
    {
        [SapName("IT_INPUT")]
        public InputItem[] Items { get; set; }
    }



    class InputItem
    {
        [SapName("WERKS")]
        public string WERKS { get; set; }

        [SapName("MATNR")]
        public string MATNR { get; set; }

        [SapName("ATWRT")]
        public string ATWRT { get; set; }

        [SapName("Z_SALE_PACK")]
        public string Z_SALE_PACK { get; set; }

        [SapName("ATWRT1")]
        public string ATWRT1 { get; set; }

        [SapName("ATWRT2")]
        public string ATWRT2 { get; set; }

        [SapName("ETDAT")]
        public string ETDAT { get; set; }

        [SapName("ZMENG")]
        public double ZMENG { get; set; }

        [SapName("ZIEME")]
        public string ZIEME { get; set; }

    }



    class ReturnTable 
    {
        [SapName("ET_RETURN")]
        public ReturnItem[] Items { get; set; }   
    }


    class ReturnItem
    {
        [SapName("STATUS")]
        public string STATUS { get; set; }

        [SapName("MESSAGE")]
        public string MESSAGE  { get; set; }
        
    }



}

只用了1秒钟，SAP中灌入了10000条数据
