Assigning properties to delegates in C#
Assigning properties to delegates in C# - this cannot be done.
So if you wanted to select a property to use at runtime, then you can use a method similar to that shown below.
public class Class1
{
string s1 = null;
string s2 = null;
private PropertyInfo _prop;
public Class1(int iPropToUse)
{
if (iPropToUse == 1)
_prop = typeof(Class1).GetProperty("PropOne");
else
_prop = typeof(Class1).GetProperty("PropTwo");
}
public string PropOne
{
get {return s1; }
set {s1 = value;}
}
public string PropTwo
{
get {return s2;}
set {s2 = value;}
}
public void SetStringValue(string s)
{
if (_prop != null) _prop.SetValue(this,s,null);
}
public string GetStringValue()
{
if (_prop != null) return (string) _prop.GetValue(this,null);
else return "no property set";
}
static void Main(string[] args)
{
Class1 o1 = new Class1(1);
o1.SetStringValue("Hello");
Console.WriteLine(o1.GetStringValue());
Class1 o2 = new Class1(2);
o2.SetStringValue("World");
Console.WriteLine(o2.GetStringValue());
int i = Console.Read();
}
}
