我对asp.net和委托有一个问题，它给了我以下错误：
Date:10/07/2014 11:54:49
Page Name: Global.asax
Source: System.Web
Target Method: ValidateInputIfRequiredByConfig
Message: The length of the query string for this request exceeds the configured maxQueryStringLength value.
Stack Trace: at System.Web.HttpRequest.ValidateInputIfRequiredByConfig()
at System.Web.HttpApplication.ValidateRequestExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)
这里有什么问题？
