Question

Please consider this class:

public static class Age
{    
    public static readonly string F1 = "18-25";
    public static readonly string F2 = "26-35";
    public static readonly string F3 = "36-45";
    public static readonly string F4 = "46-55";
}

I wanto to write a function that get “F1” and return “18-25”.for example

private string GetValue(string PropertyName)
....

How can I do it?

You can simply use SWITCH statement to perform above task:

public static string GetValue(string PropertyName)
{
    switch (PropertyName)
    {
        case "F1":
            return Age.F1;
        case "F2":
            return Age.F2;
        case "F3":
            return Age.F3;
        case "F4":
            return Age.F4;
        default:
            return string.Empty;
    }
}

Using Reflection, you can do like this:

public static string GetValueUsingReflection(string propertyName)
{
    var field = typeof(Age).GetField(propertyName, BindingFlags.Public | BindingFlags.Static);
    var fieldValue = field != null ? (string)field.GetValue(null) : string.Empty;
    return fieldValue;
}
