Which one is faster?

[PT Exorcist]

i remember to see in a topic i think that this first piece of code would be faster than the second one:

System.Deviantart.Implementation t = this.devImplementation;

e.Graphics.FillRectangle(new SolidBrush(Color.FromArgb(t.MaskAlpha, t.MaskRed, t.MaskGreen, t.MaskBlue)), 0, 0, this.Width, this.Height); 

second:

System.Deviantart.Implementation t = this.devImplementation;

e.Graphics.FillRectangle(new SolidBrush(Color.FromArgb(this.DevImplementation.MaskAlpha, this.DevImplementation.MaskRed, this.DevImplementation.MaskGreen, this.DevImplementation.MaskBlue)), 0, 0, this.Width, this.Height);
