C# 使用stringbuilder向表中添加信息，然后对ASP.Net进行排序
我对C和ASP.Net有点陌生 我想制作一个web应用程序，在其中我可以将信息添加到要显示的html表中。 MySQL和类似的东西没有什么真正的进步，只是一个简单的例子 我希望能够添加这些人，然后在以后按性别对他们进行排序，男性，女性，但不管我怎么做，显示他们所有人的列表都有效，但其他两个不行。 当我添加一个男性时，我可以看到男性，但是如果我添加一个女性，男性消失，另一个表中出现一个女性。等等 下面是它正在做的事情的gif： 我试着这样做： WebForm1.aspx.cs WebForm1.aspx 我听说也许使用Arraylist和GridView或其他更容易一些，但我不知道怎么做C# 使用stringbuilder向表中添加信息，然后对ASP.Net进行排序,c#,asp.net,arraylist,html-table,C#,Asp.net,Arraylist,Html Table,我对C和ASP.Net有点陌生 我想制作一个web应用程序，在其中我可以将信息添加到要显示的html表中。 MySQL和类似的东西没有什么真正的进步，只是一个简单的例子 我希望能够添加这些人，然后在以后按性别对他们进行排序，男性，女性，但不管我怎么做，显示他们所有人的列表都有效，但其他两个不行。 当我添加一个男性时，我可以看到男性，但是如果我添加一个女性，男性消失，另一个表中出现一个女性。等等 下面是它正在做的事情的gif： 我试着这样做： WebForm1.aspx.cs WebForm1.a
请帮助。这里是我创建的一个示例。希望能有帮助。你可以下载它 它使用可排序的GridView控件，单击标题文本和用于数据访问的SqlDataSource

嘿，谢谢你的回答，但我现在有个新问题。不知何故，我似乎无法连接到SQL server。我说：在当前web请求的执行过程中生成了一个未处理的异常。有关异常的起源和位置的信息可以使用下面的异常堆栈跟踪来识别。然后[SqlException 0x80131904:无法打开登录请求的数据库1\u 1。登录失败。用户'ISMAIL-PC\imano\u 000'登录失败。]抱歉，我忘了在评论中提及您。
