类型或命名空间名称'动态'找不到 [英] The type or namespace name 'dynamic' could not be found
问题描述
微软的Visual Studio 2010旗舰版（版本10.0.40219.1 SP1Rel）。
Microsoft Visual Studio 2010 Ultimate (Version 10.0.40219.1 SP1Rel).
Microsoft .NET Framework版本4.5.50709 SP1Rel
Microsoft .NET Framework version 4.5.50709 SP1Rel
我要编译的.NET Framework 4.0。
I am compiling to .net framework 4.0.
每当我尝试使用动态或VAR数据类型，我得到在主题行中显示的错误：
Whenever I try to use the dynamic or var data types, I get the error shown in the subject line:
类型或命名空间名称'动态'找不到。
The type or namespace name 'dynamic' could not be found.
类型或命名空间名称'变种'找不到。
The type or namespace name 'var' could not be found.
我想使用JsonFX来分析，我从另一个Web服务接收数据。有时候数据会重新present一个消息，有时它会重新present一个跟踪。根据这一 JsonFx文档，我应该能够效仿的序列化/从动态类型（默认为.NET 4.0）：
I am trying to use JsonFX to parse data that I receive from another web service. Sometimes with data will represent a "message", and sometimes it will represent a "track". According to this JsonFx Documentation, I should be able to follow the example for "Serialize to/from dynamic types (default for .NET 4.0):"
我添加了一个页面到我的网站被称为测试。下面的code块是从Test.aspx.cs 在code我想使用是这样的：
I added a page to my site called test. The code block below is from Test.aspx.cs The code I am trying to use is this:
using System;
using System.Text;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using JsonFx;
using JsonFx.Json;
using Microsoft.CSharp;
public partial class Test : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string Data = "";
Data = @"[{""meta"":{""account"":""orbitinte"",""event"":""track""},""payload"":{""id"":410827200397312213,""id_str"":""410827200397312213"",""asset"":""359551031717134"",""recorded_at"":""2013-02-07T15:59:04Z"",""received_at"":""2013-02-07T16:00:37Z"",""fields"":{}}},{""meta"":{""account"":""orbitinte"",""event"":""track""},""payload"":{""id"":410827200409895125,""id_str"":""410827200409895125"",""asset"":""359551031717134"",""recorded_at"":""2013-02-07T16:00:04Z"",""received_at"":""2013-02-07T16:00:37Z"",""fields"":{}}}]";
Data = @"[{""meta"":{""account"":""orbitinte"",""event"":""message""},""payload"":{""id"":410865901198377173,""thread_id"":null,""parent_id"":410865891354345685,""id_str"":""410865901198377173"",""thread_id_str"":"""",""parent_id_str"":""410865891354345685"",""type"":""message"",""channel"":""com.mdi.services.adminProtocol"",""sender"":""359551031717134"",""recipient"":""@@server@@"",""asset"":""359551031717134"",""b64_payload"":""eyJlcnJvciI6ImNhbm5vdCBwYXJzZSBjb21tYW5kIn0="",""recorded_at"":""2013-02-07T18:34:25Z"",""received_at"":""2013-02-07T18:34:24Z""}}]";
JsonReader Reader = new JsonReader();
dynamic Output = Reader.Read(Data);
Notifications oNotifications = new Notifications();
oNotifications.ProcessNotifications(Data);
}
}
在web.config文件：
In the web.config file:
<system.codedom>
<compilers>
<compiler language="c#;cs;csharp" extension=".cs" warningLevel="4" type="Microsoft.CSharp.CSharpCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
<providerOption name="CompilerVersion" value="v4.0"/>
<providerOption name="WarnAsError" value="false"/>
</compiler>
</compilers>
</system.codedom>
我是相当新的C＃和asp.net。但是，我一直在寻找一个解决这个问题，而现在。我看到的一切提到了编译器版本和.NET Framework版本。我想我已经提供了所有的相关细节，但如果有什么事我应该加入到这个问题，请让我知道。
I am fairly new to C# and asp.net. But I've been searching for a solution to this problem for a while now. Everything I see mentions the compiler version and the .net framework version. I think I have provided all of the relevant details, but if there is anything else I should add to this question, please let me know.
推荐答案
在IIS网站配置为使用.NET 2.0？这就是它听起来像我。首先检查配置..没有你的测试工作在本地？
Is your website in IIS configured to use .NET 2.0 ? That's what it sounds like to me. Check the configuration first.. does your test work locally ?
您的编译器应该是这样的：
Your compiler should look like this:
<compiler language="c#;cs;csharp" extension=".cs" warningLevel="4" type="Microsoft.CSharp.CSharpCodeProvider, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
你的是设置为版本= 2.0.0.0
Yours is set to Version=2.0.0.0
