Documentation Incorrect

The statement under "Remarks" is not correct: If the values for Top, Bottom, Left, or Rights were set separately, then All returns -1, even if all 4 properties have the same value:
var p = new Padding( 5 );
// Here, All returns 5
p.Left = 5;
// Now, All returns -1, although all 4 properties still have a value of 5
p.All = 5;
// Now, All returns 5 again
