一个基本的错误，让我痛苦了很久

var bounds = this.CurrentModel.Bounds;
                                                            responseString
                                                                =
                                                                "{\"scenes\":[{\"name\":\"zbw911test\",\"is3D\":true,\"preferFormat\":\"jpg\",\"boundingBox\":{" +
                                                                "\"minX\":" + bounds.X + ",\"maxX\":" + (bounds.X +
                                                                bounds.SizeX) + "," +
                                                                "\"minY\":" + bounds.Y + ",\"maxY\":" + (bounds.Y +
                                                                bounds.SizeY) + "," +
                                                                "\"minZ\":" + bounds.Z + ",\"maxZ\":" + (bounds.Z +
                                                                bounds.SizeZ) + "}}]}";

 

 

",\"maxX\":" + (bounds.X + bounds.SizeX) + "," +

 

由于没有加括号，最后坐标系怎么也不对，晕了，最近
