I have a object of Myclass. I want set string value for Category Property of this object .

Answer 1

From your example:

Public Class Myclass
{
      public virtual Category Category
    {
        get;
        set;
    }
}

I am thinking you mean this:

Public Class Myclass
{
      public string Category { get; set; } // variable
      public MyClass() {}  //<- empty constructor-might be created by default .. but I like to put them in
}

then call:

Myclass cls=new Myclass();
cls.Category= "text here";

It looks like your type for the Category variable is Category instead of string?

Unless you already have a Category type somewhere that you want to use.

Hope this helps!

For example, if one of those string properties is "Name" then you just set it like this:

Myclass cls=new Myclass();
cls.Category = new Category();
cls.Category.Name = "CategoryName1";

Note that the Name property must be accessible to the calling code (eg public ).

Or you can write it like this:

Myclass cls=new Myclass();
cls.Category = new Category {Name = "CategoryName1"};

Answer 3

Is this what you meant?

public class Category
{
   public string Name { get; set; }
   public string Description { get; set; }
}


Category myCategory = new Category();
myCategory.Category.Name = "Basketball";
myCategory.Category.Description = "Played Indoors";

Answer 4

You cannot set string value to non-string field. But if you need that string inside class instance, you can write like this:

public class MyClass
{
    public Category Category { get; set; }
}

public class Category
{
    public Category(string name)
    {
        Name = name;
    }

    public string Name { get; set; }
}

And then declare Category field of MyClass like this:

var cls = new MyClass();
cls.Category = new Category("hello");
