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

Yes, your looking for the PropertyInfo.SetValue method e.g.

var propInfo = info.GetType().GetProperty(propertyName);
if (propInfo != null)
{
    propInfo.SetValue(info, value, null);
}
