SQL Server没有找到序列化程序集

Question

我正在尝试部署一个调用Web服务的UpdateContries SQL CRL过程,请按照此处的帮助进行操作

• http://www.elzaris.co.za/using-web-services-in-sql-server-clr-assemblies/
• http://msdn.microsoft.com/en-us/library/84b1se47.aspx
• footheory.com/blogs/bennie/archive/2006/12/07/invoking-a-web-service-from-a-sqlclr-stored-procedure.aspx

所以基本上我在Visual Studio 2010上有一个Visual C#SQL CLR数据库项目,它有一个简单的过程调用外部Web服务,该服务被添加为Web引用.

我已将项目复制到包含SQL Server 2008数据库的远程服务器.

在项目属性中,我将生成序列化程序集设置为"打开",将数据库权限级别设置为"外部",并且已激活部署代码.

同样在项目中,我手动创建并删除序列化程序集,如下所示:

PreDeployScript.sql

IF EXISTS (SELECT [name] FROM sys.assemblies WHERE [name] = N'ReportsWebServicesXML')
    DROP ASSEMBLY [ReportsWebServicesXML];
GO

PostDeployScript.sql

CREATE ASSEMBLY [ReportsWebServicesXML]
    FROM 'E:\Projects\Reports\ReportsWebServices\ReportsWebServices\bin\Debug\ReportsWebServices.XmlSerializers.dll'
    WITH PERMISSION_SET = SAFE;
GO

项目构建和部署成功,我可以在Assembies文件夹下的Visual Studio 2010 Server资源管理器中看到ReportsWebServices和ReportsWebServicesXML,但是当我尝试运行该过程时,它仍然返回以下错误:

任何提示？

我在这里找到了解决方案...... http://www.cstruter.com/blog/320

"当序列化设置设置为auto/on并且您正在使用项目中的Web服务时,会自动在输出文件夹中生成序列化程序集(例如SourceAssembly.XmlSerializers.dll),您需要在SQL中注册在以下代码段中看到:

CREATE ASSEMBLY CLRProcedures FROM 'C:\demos\CSTruter.com\CLRSQL\bin\Release\SourceAssembly.dll' 
WITH PERMISSION_SET = UNSAFE
GO
CREATE ASSEMBLY CLRSerializer FROM 'C:\demos\CSTruter.com\CLRSQL\bin\Release\SourceAssembly.XmlSerializers.dll' 
WITH PERMISSION_SET = UNSAFE
GO
CREATE PROCEDURE Test
AS EXTERNAL NAME [CLRProcedures].[CSTruter.com.StoredProcedures].[Test]"
