通过InjectionConstructor传递asp.net网页的当前实例

Question

public class LogUtil : ILogUtility
{
   ... 
   public LogUtil(System.Type classType) 
   ....
}

From my WebForm1.aspx page code behind, PageLoad event, I am able to do the following successfully..

LogUtil logger = new LogUtil(this.GetType());

But when I attempt the following code from WebForm1.aspx, on pageload event..

var container = new UnityContainer();
System.Type type = this.GetType();

container.RegisterType<ILogUtility, LogUtil>(new InjectionConstructor(this.GetType()));  <--Error

at the above line, I get the following error...

The type LogUtil does not have a constructor that takes the parameters (WebForm1).

What am I doing wrong? How can I pass in the current instance of class via InjectionConstructor? Why am I able to pass in this.GetType() successfully directly into LogUtil constructor but I am uanble to do it via InjectionConstructor???

Answer 1

On your Logger class, your type is the Logger class, so it works. It doesn't work on the webform, because this.GetType() is returning the type webform.

Answer 2

I was able to fix it by updating the constructor signature of my class as follows:

public class LogUtil : ILogUtility
{
   ... 
   public LogUtil(object classType)  
   ....
}
