Pointer to Property

public class Class1

{

             private int member;



	public int Member

	{

	             get

		{

		return this.member;

		}

		set

		{

			this.member =value;

	}

}//end class





public class Class2

{

	private int externalClassMember;



	public int ExternalClassMember

	{

		get

		{

			return this.externalClassMember;

		}

		set

		{

			this.externalClassMember = value;

		}

	}

		public void SetMember(ref int member)

	{

		this.externalClassMember = member;

	}

} //end class



public class Test

{

            Class1 testClass1 = new Class1();

	Class2 testClass2 = new Class2();



	testClass1.Member = 10;



	testClass2.SetMember(ref testClass1.Member);

	testClass2.ExternalClassMember = 8;



	Console.WriteLine(testClass1.Member.ToString());

}

I want the property in class2 to point to the property in class1.

Problem is, I get an error that properties cannot be passed as a ref parameter.

A property is really designed to encapsulate or mimic a simple member variable of the class or structure; part of this means there should be no unexpected side effects when assigning or retrieving a value via a property - passing by reference would break this rule.

 

It may help if you gave a bit more detail about what you are trying to do and see if anyone has an alternate suggestion.

If I get you right, you want Class2 to hold a reference to an instance of Class1 - maybe pass that in the constructor. Then your property in Class2 just returns the value from Class1. Let me know if that doesn't make sense and I can throw out a sample - or maybe that's not even what you want.

Ok, I've decided that what Im doing is bad design anyway. I'll just stick with what I have. Thank you for your time.
