1、图标在Dev源码的存储路径：

Sources D.x.u 15.1.3\DevExpress.Images\Images

 

2、引用DevExpress.Images.v15.1.dll文件，代码获取图标方法：

ImageCollection imageCollection = new ImageCollection();

imageCollection.Images.Add(DevExpress.Images.ImageResourceCache.Default.GetImage("images/actions/add_16x16.png"));

DevExpress.Images.ImageResourceCache.Default.GetImageById("Add", DevExpress.Utils.Design.ImageSize.Size16x16, DevExpress.Utils.Design.ImageType.Colored)
