使用类库从主MVC应用程序创建类的对象c＃

I want to instantiate an object of a class using Activator.CreateInstance. So, I have an ASP.Net MVC project under which i have a folder called Modal and under that i have one class TestClass.cs.

我想使用Activator.CreateInstance实例化一个类的对象。所以,我有一个ASP.Net MVC项目,我有一个名为Modal的文件夹,在其下我有一个类TestClass.cs。

Now i have another Class Library project. So have i written the instantiation login inside one of the class of my Class Library project and copy the .dll file inside my main ASP.Net MVC project.

现在我有另一个类库项目。所以我在我的类库项目的一个类中编写了实例化登录,并将.dll文件复制到我的主ASP.Net MVC项目中。

Now from my main project i requested to my recently add Class Library project to create an Object of the class by passing FullyQualified name of my class.

现在从我的主项目我请求我最近添加的类库项目通过传递我的类的FullyQualified名称来创建类的对象。

EX:

ASP.Net MVC Project

ASP.Net MVC项目

------------------------------
`
namespace MyProject.Modal
{
    public class TestClass
    {
        public TestClass()
        {
        }
    }
}
`

Class Library Project Code

namespace SpringNet.FactoryContext
{
   public class CreateInstance
   {        
     public Object GetClass(string FullyQualifiedName)
     {
        Object NewClassType = null;
        Type ClassName = Type.GetType(FullyQualifiedName);
        NewClassType = Activator.CreateInstance(ClassName);
        return NewClassType;
     }
   }
}

Now i build my Class library project and added reference to my ASP.Net MVC Project and tries to create the object.

CreateInstance instance = new CreateInstance();
var NewObject = instance.GetClass("MyProject.Modal.TestClass");

After calling this i am getting exception

在打电话给我后,我得到了例外

Type ClassName = Type.GetType(FullyQualifiedName);

Type ClassName = Type.GetType(FullyQualifiedName);

at this line only i am not able to get the type of class what i am requesting for.

在这一行只有我无法得到我要求的类型。

Please help. Thanks in advance.

请帮忙。提前致谢。

You can try this one:

你可以尝试这个:

namespace SpringNet.FactoryContext
{
   public class CreateInstance
   {        
     public Object GetClass(string assemblyName,string className)
     {
        return Activator.CreateInstance(assemblyName, className);
     }
   }
}

And then

 CreateInstance instance = new CreateInstance();
    var NewObject = instance.GetClass("MyProject", "MyProject.Modal.TestClass");

Updated: Why Type.GetType return null

更新:为什么Type.GetType返回null

Type.GetType("namespace.a.b.ClassName") returns null

Type.GetType(“namespace.a.b.ClassName”)返回null
