这是我对global.asax的VB代码
<%@ Application Language="VB">
<script runat="server">
Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
' Code that runs on application startup
Application("CS") = "server=myServer; user id=myUser; password=MyPaas; database=myData; pooling=true"
End Sub
Sub Application_End(ByVal sender As Object, ByVal e As EventArgs)
' Code that runs on application shutdown
Application("CS") = ""
End Sub
Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
' Code that runs when an unhandled error occurs
End Sub
Sub Session_Start(ByVal sender As Object, ByVal e As EventArgs)
' Code that runs when a new session is started
End Sub
Sub Session_End(ByVal sender As Object, ByVal e As EventArgs)
' Code that runs when a session ends.
' Note: The Session_End event is raised only when the sessionstate mode
' is set to InProc in the Web.config file. If session mode is set to StateServer
' or SQLServer, the event is not raised.
End Sub
</script>
我在VB中调用此值如下:
Dim objConn As New SqlConnection(Application("CS"))
如何在C#ASP.NET中执行此调用?
答案 0 :(得分:0)
等效的C#代码是:
SqlConnection objConn = new SqlConnection(Application["CS"]);
注意“CS”周围的[]而不是()。
或者,您可以在使用块中执行此操作:
using (SqlConnection objConn = new SqlConnection(Application["CS"]))
{
// Do your data access here
}
using块确保调用dispose(即使遇到异常)。有关using语句的更多信息,请参阅using Statement (C# Reference)。
虽然我想知道 - 你为什么要在C#中使用用VB.NET编写的Global.asax文件?
