26、列表插件，引出Excel

业务场景：仿标准产品，引出EXCEL功能；

1、打开VS，新建一个类库，具体可以参考21.1 ，1-4步

1.1、本节新增引用

Kingdee.BOS.ServiceHelper

2、

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using Kingdee.BOS.App.Data;
using Kingdee.BOS.Util;
using Kingdee.BOS.Core.List.PlugIn;
using Kingdee.BOS.Core.List;
using Kingdee.BOS.Core.DynamicForm;
using Kingdee.BOS.Core;
using Kingdee.BOS.ServiceHelper.Excel;
using System.ComponentModel;

namespace Kingdee.Bos.Excel
{
    [Description("引出Excel")]
    
    [Kingdee.BOS.Util.HotUpdate]
    
    
    public class ClassExcel:AbstractListPlugIn
    {
        string sql;
        DataSet ds;
        DataTable dt;
        
        public override void BarItemClick(BOS.Core.DynamicForm.PlugIn.Args.BarItemClickEventArgs e)
        {
            base.BarItemClick(e);
            
            //当点击按钮
            if(e.BarItemKey.Equals("YDIE_tbTest"))
            {
                //选择哪几行
                ListSelectedRowCollection selectRows = this.ListView.SelectedRowsInfo;
                
                //把获取的主键赋值给一个数组
                string[] ID = selectRows.GetPrimaryKeyValues();
                
                //设置一个空值
                string FID = "";
                
                //没有选择单据,提示
                //如果空值的长度等于0
                if(ID.Length ==0)
                {
                    this.View.ShowMessage("请选择单据", MessageBoxType.Notice);
                    return;
                }
                    //如果选择了单据
                else
                {
                    for(int i=0;i<ID.Length;i++)
                    {
                        FID = FID + ID[i].ToString() + ",";
                    }
                }
                
                //查询出FID里面的,单据编号
                sql = "/*dialect*/select FBillNo as '单据编号' from T_SAL_OUTSTOCK where fid in(" + FID.Substring(0,FID.Length -1) + ")";
                
                //执行sql
                ds = DBUtils.ExecuteDataSet(this.Context, sql);
                //把单据编号放到dt表里面
                
                dt = ds.Tables[0];
                //金蝶对Excel操作
                
                string fileName = string.Format("{0},{1}.xls", "销售出库单", DateTime.Now.ToString("hhmmssffffff"));
                
                //获取路径
                string filePath = PathUtils.GetPhysicalPath(KeyConst.TEMPFILEPATH, fileName);
               
                //获取服务器Url地址,把文件传到服务器上面,然后下载
                string fileUrl = PathUtils.GetServerPath(KeyConst.TEMPFILEPATH, fileName);
                
                using (ExcelOperation excelHelper = new ExcelOperation(this.View))
                {
                    excelHelper.BeginExport();
                    //数据内容 dt,单据编号
                    excelHelper.ExportToFile(dt);
                    //路径,保存为excel文件
                    excelHelper.EndExport(filePath, SaveFileType.XLS);
                }
                
                //打开文件下载界面
                DynamicFormShowParameter showParameter = new DynamicFormShowParameter();
                showParameter.FormId = "BOS_FileDownload";
                showParameter.OpenStyle.ShowType = ShowType.Modal;
                showParameter.CustomComplexParams.Add("url", fileUrl);
                
                //显示
                this.View.ShowForm(showParameter);
            }
        }
    }
}

3、重新生成dll

4、重新打开销售出库单列表，点按钮，下载excel，点下载，打开excel

------------------------------------------------------------------------------------

5、没有表头，添加 

select '单据编号' union all

sql = "/*dialect*/select '单据编号' union all select FBillNo as '单据编号' from T_SAL_OUTSTOCK where fid in (" + FID.Substring(0, FID.Length - 1) + ")";

6、 重新生成dll
