问题描述

| 我从以下网址下载了此代码：http://msdn.microsoft.com/zh-cn/magazine/cc164657.aspx，但它是VS2003。我正在尝试使其在VS 2010中工作。似乎有一些变化。例如，我需要在2010年实例化资源对象。这是主要代码： 
using System;
using System.IO;
using Spring.Objects.Factory.Xml;
using SpringDIExample;
namespace runner
{
class Class1
{

    [STAThread]
    static void Main()
    {
        // 1. Open the configuration file and create a new
        //    factory,reading in the object deFinitions
        using (Stream stream = File.OpenRead(\"config.xml\"))
        {
            // 2. Create a new object factory
            Spring.Core.IO.InputStreamResource resource = new Spring.Core.IO.InputStreamResource(stream,\"config\");
            XmlObjectFactory xmlObjectFactory = new XmlObjectFactory(resource);

            // 3. Call my factory class with generic label for the object
            //    that is requested. 
            IDomainObjectInterface domainObjectInterface = (IDomainObjectInterface)xmlObjectFactory.Getobject(\"DomainObjectImplementationClass\");

            // 4. Use the object just like any other concrete class.
            Console.WriteLine(\"My name is \" + domainObjectInterface.Name);
        }



        Console.ReadLine(); 
    }
}
 }
它总是在此行崩溃： 
XmlObjectFactory xmlObjectFactory = new XmlObjectFactory(resource);
这是堆栈跟踪：

任何帮助，将不胜感激。 注意配置文件是： 
<?xml version=\"1.0\" encoding=\"utf-8\" ?>
<objects xmlns=\"http://www.springframework.net\">
    <object name=\"DomainObjectImplementationClass\" 
            singleton=\"false\" 
            type=\"ImplementationClass1,SpringDIExample\" />
</objects>
    

解决方法

        尝试使用
type=\"SpringDIExample.ImplementationClass1,SpringDIExample\"
（带有名称空间的类名（如果不是
SpringDIExample
，则输入正确的名称））     ,        它告诉您在指定的程序集中找不到ImplementationClass1。 检查该类是否确实存在，拼写，名称空间和程序集名称。     ,        您可能想查看Spring.NET基于代码的新配置模型，称为CodeConfig，以替代XML。如果使用XML，则还有一个VS.NET 2010扩展，它将捕获所有这些拼写错误，并为您提供类名和属性的完成信息。 主页上有指向它的链接-http://www.springframework.net/ 期刊http://www.opensource-central.com/上有一篇有关CodeConfig的文章。 标记
