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10000InputItem[] 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
