C# get and set property by variable name

Question

Is there any way to do this? I try to test if a property of an object exists and if it does, I want to set a value to it. (Maybe the complete idea is bad, if true - why?)

Answer 1

var propertyInfo = info.GetType().GetProperty(propertyName);
if (propertyInfo != null)  //this probably works. Yes it is
  {
        propertyInfo.SetValue(info, value, null);
  }
