.net Hello World webmethod中的异常

.net Hello World webmethod中的异常,.net,web-services,.net,Web Services,我在WS(asmx)中遇到一个异常,它说: System.IndexOutOfRangeException: Index was outside the bounds of the array. at System.Web.Services.Protocols.HttpServerType..ctor(Type type) at System.Web.Services.Protocols.HttpServerProtocol.Initialize() at System.Web

我在WS(asmx)中遇到一个异常,它说:

System.IndexOutOfRangeException: Index was outside the bounds of the array.
   at System.Web.Services.Protocols.HttpServerType..ctor(Type type)
   at System.Web.Services.Protocols.HttpServerProtocol.Initialize()
   at System.Web.Services.Protocols.ServerProtocol.SetContext(Type type, HttpContext context, HttpRequest request, HttpResponse response)
   at System.Web.Services.Protocols.ServerProtocolFactory.Create(Type type, HttpContext context, HttpRequest request, HttpResponse response, Boolean& abortProcessing)

我正在从浏览器调用这个方法,它是一个
HelloWorld()
web方法,它什么都不做

我的web服务代码中确实有一些东西出错了。我删除了这个项目,重新创建了它,一切正常。对不起

即使webmethod没有做任何事情,我也会包括定义,以及关于如何调用它的更多细节?
