How to Load an assembly from a file and call the metods of a class

• Step 1: Add the reflection namspace
  using System.Reflection;
  
  Step 2: Load the assembly from the file
  Assembly testAsm = Assembly.LoadFrom(@"C:\AddList.dll");
  
  
• 
  Creates the assembly object by calling LoadFrom method in the assembly class and pass the path of the assembly as a parameter.
  
  Step 3 :Create the type object
  Type testType = testAsm.GetType("Blog.Sample.ListCreator");
  
  Call the GetType function of the assembly class to create the Type.In above example there is a namspace called Blog.Sample and class called ListCreator.
  
  Step 4:Create the instance of the Class
  object testObj = Activator.CreateInstance(testType);
  
  Use Activator.CreateInstance method to create the instance of the required class by passing the Type object which we created in the above step.
  
  Step 5: Call the method
  testType.InvokeMember("CreatList", BindingFlags.Default BindingFlags.InvokeMethod, null, testObj, new object[] { "BlogSample", "AssemblyBlog" });
  
  Use the Type.InvokeMember to call the method in the class of loaded assembly.
  
  Parameter Details:
  1, Name of the Method (Ex: "CreateList")
  2, Binding Flag(We are invoking a method so it will be BindingFlags.InvokeMethod)
  3, Binding object - you can pass null
  4, Target Object - which class's method need to be called (Object which is created by Activator.Creatinstance method - instance of the class)
  5, Object Array of parameters for method (Above passed two string parameters)
