我一直致力于将 Secugen 指纹识别器和 API 实施到无家可归者收容所的 ASP.NET 网站中，这让我抓狂。我正在使用 FDx SDK Pro for Windows API，并且我有自定义 COM 组件（通过 OCX 文件），可将 activeX 控件导入到我的工具箱中。但是，只有当我创建 Windows 应用程序然后创建 Windows 窗体时，才能使用这些控件。我需要将这些控件放在网络表单中。如果我尝试将它们放入网络表单中，activeX 工具会变灰并且不允许我这样做。有一个 .htm 示例，它正是我正在寻找的，所以我知道这是可能的，但我只是无法说出依赖项是什么。我只是不熟悉 .NET 和程序集库。这是 API 附带的自述文件，其中包含它所拥有的不同文件。我不确定是否必须先创建一个 Windows 表单，然后将其作为对象放入我的网站中。我尝试将“SecuGen.FdxSdkPro.Windows.dll”文件放入我的 bin 文件夹中，但是当我运行它时，我在运行它时收到以下错误。任何意见都将不胜感激，并让我知道上传 .htm 示例或提供代码是否有用。

Assembly Load Trace: The following information can be helpful to determine why the assembly 'SecuGen.FDxSDKPro.Windows' could not be loaded.
=== Pre-bind state information ===
LOG: DisplayName = SecuGen.FDxSDKPro.Windows
(Partial)
WRN: Partial binding information was supplied for an assembly:
WRN: Assembly Name: SecuGen.FDxSDKPro.Windows | Domain ID: 5
WRN: A partial bind occurs when only part of the assembly display name is provided.
WRN: This might result in the binder loading an incorrect assembly.
WRN: It is recommended to provide a fully specified textual identity for the assembly,
WRN: that consists of the simple name, version, culture, and public key token.
WRN: See whitepaper http://go.microsoft.com/fwlink/?LinkId=109270 for more information and common solutions to this issue.

确保您的应用程序是在 32 位平台目标中构建的
我不小心有两个帐户。首先，您必须确保将 SDK 安装在正确的位服务器上。我最终采用了 active-x 控件并将它们嵌入到 Web 表单中。然后，当捕获指纹并将其转换为字符串并通过ajax发送到服务器时。
然后我遇到了一个问题，SDK 没有正确解密字符串以进行比较的功能。我联系了 Secugen，他们非常乐意将我的请求转给工程师，然后工程师向我提供了另一个包含缺少功能的 .dll 文件。有一天我可能会在 GitHub 上发布一些源代码。当我这样做时，我会用链接更新它！
如果您在 Windows 应用程序中遇到此问题，尤其是在生产中，请检查是否安装了 microsoft c++ 可再发行组件。必须安装 2015，它才可以工作。
