下面给出了一个合并功能，该功能旨在合并文件夹中的所有docx文件并生成合并的文件。

public  void Merge()
{  
    try
    {

        string sid = Request.QueryString["studid"];
        string stud = sid.ToString();

        string ds = HttpContext.Current.Server.MapPath(("~\\StudentBinder") + "\\Temp4\\");
        if (Directory.Exists(ds))
        {
            DirectoryInfo d = new DirectoryInfo(ds);
            FileInfo[] Files = d.GetFiles("*" + stud + "*.docx");

              // stud added for differentiating b/w users

            string[] filepaths = new string[Files.Length];
            int index = 0;

            foreach (FileInfo file in Files)
            {
                filepaths[index] = file.Name;
                index++;
            }


                using (WordprocessingDocument myDoc = WordprocessingDocument.Open(Server.MapPath(filepaths[0]), true))

                {
                    for (int i = 1; i < filepaths.Length; i++) …

此查询返回无法绑定的多部分标识符

table2.AId and  table1.LId = table2.LId

查询是

insert into table1(col1)
select col2 from table2
where table1.AId = table2.AId and  table1.LId = table2.LId;

非常感谢你的帮助
