为什么我会收到此错误？我该如何修复它？我从我开始做的应用程序中的 Web.config 进行连接，但我完成了学校问题，因为这是团队的努力。老师告诉我，我应该把它放在网上，这样我的连接就可以很好地建立，但如果 publicToken 或其他东西在写这行时这个邪恶的东西被星号括起来，那就不行了。我需要指出我写错了，请指出，谢谢。

Why do I get this error? How I can fix it? I'm connecting from Web.config in an application that I started to do but I finish school issues because it is a team effort. The teacher has told me I should put that online so that my connection is well made but not if publicToken or something else this evil at the time of writing the line is enclosed in asterisks. I need to indicate that I am writing wrong Please will thank you.

在 .NET 中，不存在诸如
System.Data.SqlClient, Version=10.50.1600, ...这样的程序集。 SqlClient 是标准 .NET Framework 发行版的一部分。例如，System.Data.SqlClient.SqlConnection:
In .NET there is no such assembly as
System.Data.SqlClient, Version=10.50.1600, .... SqlClient is the part of standart .NET Framework distribution.For example, System.Data.SqlClient.SqlConnection:
您是否检查过以确保指示的 dll 正在部署并且版本号与您上面指定的版本匹配？这个错误非常明显。系统在此行找不到代码引用的程序集。
Have you checked to make sure that the dll indicated is being deployed and that the version number matches the version you specify above? The error is pretty clear. The system can't find the assembly that the code refers to on this line.
那么，您可以浏览GAC（全局程序集缓存）来满足程序集数据。从命令提示符处使用以下命令：
这会列出 GAC 的内容以及您需要的信息。
Well, you can browse the GAC (Global Assembly Cache) for meet the assembly data. Use the following command from de command prompt :
This list the content of the GAC with the information that you need.
