Question

我对 Sharepoint SOM 非常陌生，需要您对 Sharepoint 内部部署（2019 标准版）SPItemEventReceiver 的支持。目标是在项目添加到列表后立即在 SQL DB 上执行更新或插入。我想将用户插入的值用于列出项目（来自属性）并发送到表格。你可以在下面找到我的一段代码。它部署没有任何问题，但在调试时甚至不会返回错误。看起来根本没有打开连接。是否允许在 EventReceiver 中执行这样的代码？也许是一些安全问题？

        public override void ItemAdded(SPItemEventProperties properties)
        {
            SPListItem currentItem = properties.ListItem;
            string sqlserver = "dbserver01.contoso.com";
            string sqldatabase = "CRM";

                string cases = string.Format(
                    "if exists (select * from dbo.{0} where spID = '{1}') " +

                    "VALUES ('{1}', '{3}', '{4}') end",
                    sqltable, currentItem["ID"], currentItem["Company Name"], currentItem["VAT ID"],
                    currentItem["EMAIL"]);
                sbin.Append(cases);
                String sql = sbin.ToString();
                SqlCommand comm = new SqlCommand(sql, conn);
                comm.ExecuteNonQuery();
                conn.Close();

                //base.ItemAdded(properties);
            }
        }
    }
}

共享点列表到 SPEventReceiver 上的 sql 数据库
