为什么我得到这个错误没有足够的内存资源来处理这个命令？

Question

在我的网站中使用 ASP.NET MVC + webforms C# 和水晶报表，

当我点击按钮使用水晶报告打印报告时，我收到了这个错误

"没有足够的内存资源来处理这个命令"

每 2 天我收到此错误，我通过重新发布网站解决了它，但我需要永久解决方案

这是网络表单中使用的代码：

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)

                TXTORDERID.Text = Request.QueryString["order_number"].ToString();
                TXTDEPTID.Text = Request.QueryString["deptid"].ToString();
                TXTTESTID.Text = Request.QueryString["testid"].ToString();
                TXTCULTURE.Text = Request.QueryString["Culture"].ToString();
                
                ParameterFields paramFields = new ParameterFields();
                ParameterField paramField = new ParameterField();
                ParameterDiscreteValue paramDiscreteValue = new ParameterDiscreteValue();
                ParameterDiscreteValue paramDiscreteValue1 = new ParameterDiscreteValue();
                ParameterField parameterField1 = new ParameterField();

                if (Session["UserCustid"] != null && Convert.ToInt32(Session["UserCustid"]) > 0)

这是错误页面：

我需要您的帮助并解决此错误并停止服务器上的接收错误？

我试图关闭并处理报表文档，但运行报表时总是出错：对象引用未设置为实例对象错误

我将把 close 和 dispose 的代码放在哪里，不会出现这个错误

对象引用未设置到实例对象错误？

reportDocument.Close(); 
reportDocument.Dispose(); 

我检查了这个链接并在服务器注册表中将 Printjoblimit 的值更改为 1500 是否正确？

Answer 1

在页面加载 void 之后添加此 void 希望这将解决错误：

protected void Page_Unload(object sender, EventArgs e)
 {
     if (reportDocument != null)
      {
              reportDocument.Close(); 
              reportDocument.Dispose();  
              reportDocument = null;
       }
 }

还有关于注册表中的打印作业限制参数，例如尝试将值增加到 9000 并检查这是路径：

“HKEY_LOCAL_MACHINE\SOFTWARE\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Report Application Server\InprocServer”
