Pass property itself to function as parameter in C#

Question

I am looking for a method to pass property itself to a function. Not value of property. Function doesn\'t know in advance which property will be used for sorting. Simplest w

Answer 1

I would like to give a simple, easy to understand answer.

Function's parameter is this: System.Func

And we pass the Property like this: Function(x => x.Property);

Here is the code:

class HDNData
{
    private int m_myInt;
    
    public int MyInt
    {
        get { return m_myInt; }
    }
    
    public void ChangeHDNData()
    {
        if (m_myInt == 0)
            m_myInt = 69;
        else
            m_myInt = 0;
    }
}

static class HDNTest
{
    private static HDNData m_data = new HDNData();
    
    public static void ChangeHDNData()
    {
        m_data.ChangeHDNData();
    }
    
    public static void HDNPrint(System.Func dataProperty)
    {
        Console.WriteLine(dataProperty(m_data));//Print to console the dataProperty (type int) of m_data
    }
}

//******Usage******
HDNTest.ChangeHDNData();
//This is what you want: Pass property itself (which is MyInt) to function as parameter in C#
HDNTest.HDNPrint(x => x.MyInt);
