忽略与可执行文件位于同一文件夹中的程序集 .dll

Question

我有一个 .NET 应用程序，如果我将 MySql.Data.dll 程序集与可执行文件放在同一文件夹中，它会崩溃，但如果我移动它，它可以正常工作。同一文件夹中的不同可执行文件依赖于它，因此我需要将其保留在那里。

我该怎么做才能让应用程序忽略这个 dll？我假设我可以编辑配置文件，但我似乎找不到任何人遇到忽略本地 .dll 的问题，所以我不知道该写什么。

更让我摸不着头脑的是exception details中写的关于loaded assembly的部分。请注意，本地文件夹中的文件（我想忽略的那个）的版本是 6.9.9.0，异常状态是它要加载 6.9.5.0，而加载的文件（来自 GAC）是 6.9.8.0。

这是我的配置文件：

<?xml version="1.0"?>
<configuration>
    <connectionStrings>
        <add name="DB" connectionString="*" providerName="System.Data.EntityClient" />
    </connectionStrings>
    <startup>
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
    </startup>
</configuration>

非常感谢您的帮助。

这里的问题是程序集绑定；它会尝试多个位置，包括本地文件夹和 GAC。很难压制这一点。然而，我怀疑这里最好的选择是在配置文件中添加一个程序集绑定重定向，告诉 "fusion" 允许 6.9.9.0 代替以前的版本。例如：

  <dependentAssembly>
    <assemblyIdentity name="MySql.Data" publicKeyToken="c5687fc88969c44d" />
    <bindingRedirect oldVersion="0.0.0.0-6.9.9.0" newVersion="6.9.9.0" />
  </dependentAssembly>

忽略与可执行文件位于同一文件夹中的程序集 .dll

Ignore assembly .dll in same folder as executable

.net
