c# - 保存图形文件

Question

我正在创建一个表单应用程序，在这个应用程序中，我让用户绘制矩形、三角形、六边形等。我想将这些图形保存在一个文件中，并且我想在打开程序时使用它们。我的意思是像使用 nirmal 图形一样使用它们. 我正在选择并更改我想要的绘制对象的颜色。如果我将此文件导入我的应用程序，则能够更改它的颜色

像这样的东西。

// write
BinaryWriter Writer = new BinaryWriter(File.Open(FileName, FileMode.Create));;

Writer.Write(this.Point.X); Writer.Write(this.Point.Y); Writer.Write(this.Point.Z);
Writer.Write(this.Point.X); Writer.Write(this.Point.Y); Writer.Write(this.Point.Z);  
Writer.Write(this.Point.X); Writer.Write(this.Point.Y); Writer.Write(this.Point.Z);
Writer.Write(this.Point.X); Writer.Write(this.Point.Y); Writer.Write(this.Point.Z);    

Writer.Flush();
Writer.Close();

// read
BinaryReader Reader = new BinaryReader(File.Open(FileName, FileMode.Open));

this.Point.X = Reader.ReadDouble(); this.Point.Y = Reader.ReadDouble(); this.Point.Z = Reader.ReadDouble();    
this.Point.X = Reader.ReadDouble(); this.Point.Y = Reader.ReadDouble(); this.Point.Z = Reader.ReadDouble();    
this.Point.X = Reader.ReadDouble(); this.Point.Y = Reader.ReadDouble(); this.Point.Z = Reader.ReadDouble();    
this.Point.X = Reader.ReadDouble(); this.Point.Y = Reader.ReadDouble(); this.Point.Z = Reader.ReadDouble();

Reader.Close();
