我如何确保我的 WebPart 被发现并注册为安全的？

Question

在调试我的 WebPart 以查看其控件未显示的原因时，我将页面置于浏览器中的编辑模式以首先删除 WebPart 的所有多余实例，以便我逐步执行 CreateChildControls() 等。方法只有一次。

虽然这样做（将页面置于编辑模式），但我看到每个 WebPart 都包含以下错误消息：

Web 部件错误：无法显示或导入此页面上的 Web 部件或 Web 表单控件。找不到类型 WebFormPDFGen.WebFormPDFGenWebPart.WebFormPDFGenWebPart、WebFormPDFGen、Version=1.0.0.0、Culture=neutral、PublicKeyToken=42314blabla 或未注册为安全类型。

什么？ WebFormPDFGen.WebFormPDFGenWebPart.WebFormPDFGenWebPart 没有找到？解决方案名为 WebFormPDFGen，WebPart 名为 WebFormPDFGenWebPart，.cs 和 .webpart 文件也是如此：

WebFormPDFGenWebPart.webpart 确实包含对无法找到的实体 (WebFormPDFGen.WebFormPDFGenWebPart.WebFormPDFGenWebPart) 的引用：

<?xml version="1.0" encoding="utf-8"?>
<webParts>
  <webPart xmlns="http://schemas.microsoft.com/WebPart/v3">
    <metaData>
      <type name="WebFormPDFGen.WebFormPDFGenWebPart.WebFormPDFGenWebPart, $SharePoint.Project.AssemblyFullName$" />
      <importErrorMessage>$Resources:core,ImportErrorMessage;</importErrorMessage>
    </metaData>
    <data>
      <properties>
        <property name="Title" type="string">WebFormPDFGenWebPart</property>
        <property name="Description" type="string">My WebPart</property>
      </properties>
    </data>
  </webPart>
</webParts>

所以...是不是 Web 部件没有注册为安全的，正如错误消息的第二部分提到的那样？我需要做什么才能将其注册为安全的？

基于演练 here:

，我使用非常基本的 WebPart 在运行时遇到了同样的问题

当我将 WebPart 添加到我的测试页面时，它呈现良好 - 它具有基于该演练中的代码的预期 "Hello, world!" 消息，它只是：

[ToolboxItemAttribute(false)]
public class XMLToPDFWebPart : WebPart
{
    private string customMessage = "Hello, world!";

    [WebBrowsable(true),
     WebDescription("Displays a custom message"),
     WebDisplayName("Display Message"),
     Personalizable(PersonalizationScope.User)]
    public string DisplayMessage
    {
        get { return customMessage; }
        set { customMessage = value; }
    }

    protected override void CreateChildControls()
    {
        base.CreateChildControls();
        LiteralControl message = new LiteralControl();
        message.Text = DisplayMessage;
        Controls.Add(message);
    }

...但是当我随后在运行另一个 project/WebPart 时查看该页面时，它不仅不再欢快地鸣叫，"Hello, world!" 而是在我的后面吹响了雾号脸：

Web 部件错误：无法显示或导入此页面上的 Web 部件或 Web 表单控件。找不到类型 XMLToPDF.XMLToPDFWebPart.XMLToPDFWebPart、XMLToPDF、Version=1.0.0.0、Culture=neutral、PublicKeyToken=42f314BleeBlahBloo 或未注册为安全类型。

为什么它现在确定 WebPart 丢失或不安全，而以前显示它？

请注意，如果我现在尝试将该 WebPart 添加到页面，它会告诉我，"The operation could not be completed because the item was removed from the gallery"

清理、重建和[重新]部署似乎至少暂时修复了新的、超级简单的 WebPart：

...但我对它不会成为不受欢迎的 WebPart 的信心程度并没有完全接近珠穆朗玛峰的高度 - 也许是蒂姆山。

不过如您所见，原始 WebPart 仍然出现错误。

我建议下载 visual studio 的加载项。它被称为 CKSDev 工具

这允许您将 SharePoint 解决方案打包到 WSP 中，然后部署该包，这应该会保护您的安全控制。

CKSDEV tools

这将帮助您进行调试，并且在 SharePoint 开发方面通常很棒。他们甚至为站点模板等内容提供了一些模板，这将为您节省大量时间。

您可能需要创建一个新的 SharePoint 项目并迁移您的代码，但是一旦您让 CKSDev 开始工作，您就应该很顺利了。

另一种选择是找到您的 Web 应用程序的 web.config，并为您的解决方案抱怨的程序集添加一个安全控件，但我不会这样做，因为您在移动时会遇到同样的问题将其投入生产，当您开始使用这些文件时，很容易犯错误，这会给您带来更多痛苦。
