DevExpress.Utils.ImageCollection.ImageCollection 手动绑定图片

        // 获取图片路径
        string binPath = System.Reflection.Assembly.GetExecutingAssembly().Location;
        string filepath1 = System.IO.Path.GetDirectoryName(binPath);  //当前目录的上一级目录
        string filepath2 = filepath1.Substring(0, filepath1.Length - 4);

        this.imageCollection1.AddImage(Image.FromFile(@filepath2 + @"\images\theme.png"));  //
        this.imageCollection1.AddImage(Image.FromFile(@filepath2 + @"\images\config.png"));
        this.imageCollection1.AddImage(Image.FromFile(@filepath2 + @"\images\e3d02168.png"));
