无法加载文件或程序集'System.Web.Helpers，Version = 2.0.0.0，Culture = neutral，PublicKeyToken = 31bf3856ad364e35'或其依赖项之一

Question

我的项目正在我的本地电脑上工作。但是，当我把它放在服务器上时，我得到了那个例外。我试图检查程序集添加/删除或重新安装，但它无论如何都没有用。我发现了一些关于该主题的帖子，但他们没有帮助我，或者我无法理解它们。

Answer 1

您必须在项目的 参考 中验证是否已将标记的程序集标记为本地复制，并且在编译或部署项目时可以将其打包。< / p>

Answer 2

您可以安装/重新安装MySQL Connector或尝试以下步骤：

1）转到machine.Config。

适用于32位操作系统：

C：\的Windows \ Microsoft.NET \框架\ [版] \设置\ machine.config中

64位操作系统的

：

C：\ Windows \ Microsoft.NET \ Framework64 \ [version] \ config \ machine.config

2）然后删除或注释掉以下这些行：

<add name="MySQLRoleProvider" type="MySql.Web.Security.MySQLRoleProvider, MySql.Web, Version=6.7.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" connectionStringName="LocalMySqlServer" applicationName="/"/>

<add name="MySQLMembershipProvider" type="MySql.Web.Security.MySQLMembershipProvider, MySql.Web, Version=6.7.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" connectionStringName="LocalMySqlServer" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="true" applicationName="/" requiresUniqueEmail="false" passwordFormat="Clear" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="7" minRequiredNonalphanumericCharacters="1" passwordAttemptWindow="10" passwordStrengthRegularExpression=""/>

注意：如果使用MSSQL Server，则删除行内容，如下所示：

<add name="Microsoft SQL Server Compact Data Provider 4.0" invariant="System.Data.SqlServerCe.4.0" description=".NET Framework Data Provider for Microsoft SQL Server Compact" type="System.Data.SqlServerCe.SqlCeProviderFactory, System.Data.SqlServerCe, Version=4.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"/>

<add name="Microsoft SQL Server Compact Data Provider" invariant="System.Data.SqlServerCe.3.5" description=".NET Framework Data Provider for Microsoft SQL Server Compact" type="System.Data.SqlServerCe.SqlCeProviderFactory, System.Data.SqlServerCe, Version=3.5.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"/></DbProviderFactories>

希望这会有所帮助......

如果你能看到并告诉我我做错了什么？

我在Could not load file or assembly 'System.Web.Helpers, error on IIS 8帖子

中得到了答案

＆＃34;听起来好像MVC尚未安装在服务器上。＆＃34;

Answer 4

一些解决方案：

1. 您可以使用nuget拉入System.web.Helpers NuGet Link
2. 您可以更改当前的dll以复制本地。

Nuget解决方案因此大多数网络平台安装程序包都可以在nuget上使用，因此两者中的效果更好。
