推荐答案

如果您有访问数据层(数据库)的权限，则可以编写存储过程，该过程将检查记录是否存在，并相应地执行插入(或跳过)操作并以您喜欢的方式返回存在的内容. br/> 您可以像现在在代码中那样进行操作，但它可能不是标准编码".
不是"位于字符串内部，除了在C#端位于字符串内部外，什么都不做.它起着传递给数据库服务器的作用(将其解释为SQL语句)

或者，您也可以看到页面刷新会导致ASP.NET中的POST重复应用程序 [ ^ ]

Hi,
If u have acess to the Data Layer (database), u can write a stored procedure, which does the checking, whether the record exists, and do the insert (or skip) accordingly and return, the existence in a way u prefer.
You may do that as you do it now in the code, but it may not be the "standard coding".
"is Not" is inside a string and is doing nothing other than being inside a string, in C# side. It comes into play one passed to Database server (interprets it as SQL statements)

尝试加载页面负载！IsPostback(){//您在此处执行的任何代码}

Try to put on the Page load !IsPostback () { //whatever codes you''re doing in here }
