c# - Problems in generating random colors -
i want generate random colors in wpf , store them in array. random r; color[] colarr = new color[6]; (int = 0; < colarr.length; i++) { color c=new color(); r=new random(); r.next(); c.r = (byte)r.next(1, 255); c.g = (byte)r.next(1, 255); c.b = (byte)r.next(1, 255); c.a = (byte)r.next(1, 255); c.b = (byte)r.next(1, 255); colarr[i] = c; } but elements of array represent 1 single color. when debugged code, found random colors every element, when code executed(not in debug mode) same color generated. makes clear code correct, there problem while execution. edit : how can increase randomness of colors generated? the problem making new instance of random each run. should set once. the default seed random system time, same if repeat fast loop; time won't change lot. if set @ start, random work expected. i suggest use r.next(0, 256) , since give value ranging 0 255. also, call r.next() after definition of color c unnecess
