sqlbulkcopy仅复制首页而忽略其余页面

Question

您好，最近我一直在尝试开发一个程序，使用sqlbulkcopy将excel数据导入SQL Server数据库，但是它仅复制第一页（如果打印，至少会复制第一页）

string ssqltable = "Test";
        string myexceldataquery = "Select [Employee Name],[DOB],[Email],[Mobile] from [Sheet1$]";
        try
        {
            string excelconn = @"provider=microsoft.ACE.OLEDB.12.0;data source=" + excelFilePath +
            ";extended properties=" + "\"excel 12.0;hdr=yes;\"";
            sqlconn.Open();
            OleDbConnection oledbconn = new OleDbConnection(excelconn);
            OleDbCommand oledbcmd = new OleDbCommand(myexceldataquery, oledbconn);
            oledbconn.Open();
            OleDbDataReader dr = oledbcmd.ExecuteReader();
            SqlBulkCopy bulkcopy = new SqlBulkCopy(sqlconn);
            bulkcopy.DestinationTableName = ssqltable;
            while (dr.Read())
            {
                bulkcopy.WriteToServer(dr);
            }
            dr.Close();
            oledbconn.Close();
