有没有办法通过委托直接调用属性设置器？

Question

I am working with Windows Forms, and many times have bumped into (as I understood it) the necessity to write wrapping functions around properties of the UI components, so that they (the properties) could be set from another thread by invoking their wrappers.

However, one thing doesn't give me rest. Are not the setters of properties actually functions themselves? If they are, could a Delegate be formed around them without resorting to writing wrappers, and then said delegate be invoked from another thread?

Answer 1

Yes, this is possible. Use the PropertyInfo.GetSetMethod function to retrieve the set accessor for the property, and then create a delegate to invoke it.

Or even simpler yet, you could use the PropertyInfo.SetValue function to set the value directly.

Answer 2

I can't find the real solution for this question but I figured it out. I sometimes need it myself but Google fails me.

Example:

public string Blah
{
    get
    {
        if (InvokeRequired)
            return (string) Invoke(new Func<string>(() => Blah));
        else
            return Text;
    }
    set
    {
        if (InvokeRequired)
            Invoke(new Action(() => { Blah = value; }));
        else
            Text = value;
    }
}
