无法加载动态生成的序列化程序集;SQLCLR存储过程中出现错误

当我尝试从SQL Server 2008 R2执行c# CLR存储过程时，我得到以下错误:

Msg 6522，级别16，状态1，过程PrintShippingDocLabelsToPDF，第0行
.NET Framework在执行用户定义例程或聚合"PrintShippingDocLabelsToPDF"时发生错误:
系统。InvalidOperationException: 无法加载动态生成的序列化程序集。在某些托管环境中，程序集加载功能受到限制，请考虑使用预生成的序列化程序。

请参阅内部异常获取更多信息。——>

先。fileloadexcexception: LoadFrom()， LoadFile()， Load(byte[])和LoadModule()被主机禁用
System.IO.FileLoadException:

这是我的理解，这发生正是因为我试图写入网络共享上的文件。我已经查看了以下来源:https://msdn.microsoft.com/en-us/library/ms345106(v=sql.105).aspx，从CLR存储过程中访问Sql FILESTREAM，但我仍然迷路了。

我所需要做的就是在网络共享上编写几个从SSRS到xxx.pdf文件的报告(其中xxx代表自定义名称)。下面是这个功能的代码，我相当确定下面的部分是导致错误的原因。

// Create a file stream and write the report to it
using (FileStream stream = File.OpenWrite(strFilePath + strFileName))
{
    stream.Write(results, 0, results.Length);
} // END using (FileStream stream = File.OpenWrite(StoredProcedures.strFilePath + StoredProcedures.strFileName))

下面是完整的程序。谁能给我点指示吗?我的工作期限很紧。作为临时解决方案，也许可以将这些报告写入临时表，然后使用SSIS包将它们移动到文件夹中。如果这是可能的，有人能给我一个指针，我将如何存储这些文件(varbinary(最大这些文件大约60KB-150KB的大小)?
