And I have another namespace MyNamespace2. I want to use MyNamespace1. But when I use 

using MyNamespace1;

it is not recognizable.I want to know how to do this.

MSDN is your friend in learning about this.

The namespace keyword is used to declare a scope.

namespaces used to organize it's many classes

namespace N1     // N1
{
    class C1      // N1.C1
    {
        class C2   // N1.C1.C2
        {
        }
    }
    namespace N2  // N1.N2
    {
        class C2   // N1.N2.C2
        {
        }
    }
}

Using Namespaces (C# Programming Guide)

Check your accessibility level of your namespace. If it is in same project then you can access it directly. 

using YourProjectName.NamespaceThatYouCreated;

If it is another project like dll etc then add reference to that library or project. access namespace as:

using AnotherProject.CreatedNameSpacename;

If both of your name spaces are in different project then you must add the reference of the other project to access it's namespace. In your case add the project reference of MyNamespace1 to the project the project of MyNamespace2.

and this one in particular: http://www.csharp-station.com/Tutorials/Lesson06.aspx

Also, what I've discovered, if you're using asp.net you might need to change the property "Build action" of the class you wish to use in your page to "Compile".
