Why Can WebMethod Access Session State Without EnableSessionState?

由 半腔热情 提交于 2019-12-01 15:18:50
I have a method on a page marked as a [WebMethod] that uses some session state as part of its operation. After I wrote this code, I suddenly had a flash of memory that you need to use EnableSessionState when you use session state in a [WebMethod] (e.g. see here: http://msdn.microsoft.com/en-us/library/byxd99hx.aspx ). But it seems to be working fine. Why? Sample code behind: protected void Page_Load(object sender, EventArgs args) { this.Session["variable"] = "hey there"; } [System.Web.Services.WebMethod] public static string GetSessionVariable() { return (string)HttpContext.Current.Session[

How to get the instance name of an object

由 妖精的绣舞 提交于 2019-12-01 08:54:28
问题 I use the below code to write code to query a web method in a specified interval. now in the this.Poll function I have to do this.tmo = setTimeout(this.strInstanceName + ".Poll()", this.iInterval); instead of this.tmo = setTimeout(this.Poll(), this.iInterval); because IE looses the this pointer after setTimeout So I have to pass the class it's instance name: var objPoll = new cPoll("objPoll"); How can I get the instance name without passing it as parameter ? I want to have it outta there ! <

setting jsonSerialization maxJsonLength in ASP.net Web.Config gives 500 error

由 浪尽此生 提交于 2019-12-01 06:11:01
So, I keep getting the 500 - Internal server error page on my .net site when I set the maxJsonLength in my web.config. I'm modifying the .config because even though I use MaxJsonLength = Int32.MaxValue on my vb.net JavaScriptSerializer, I'm still getting InvalidOperationException for a large dictionary i'm trying to transmit even though it's well below the 4GB the MaxJsonLength @ Int32.MaxValue allows or even the supposed 4mb default limit. I'm using toolkitscriptmanager if that means anything. <system.web.extensions> <scripting> <webServices> <jsonSerialization maxJsonLength="2147483647"/> <
