C＃類和結構

Question

我有在C＃中的一些問題，系列化 有一些代碼：

public struct CoOrds 
{ 
    public double x, y, z; 

    public CoOrds(double p1, double p2, double p3) 
    { 
     x = p1; 
     y = p2; 
     z = p3; 
    } 
} 
public struct printColor 
{ 
    public int r, g, b; 

    public printColor(int p1, int p2, int p3) 
    { 
     r = p1; 
     g = p2; 
     b = p3; 
    } 
} 
[Serializable] 
public abstract class shape : ISerializable 
{ 
    public int borderStyle=1;   
    /* ===============================COLOR PARAMETERS================================ */ 
    public printColor colorRGB = new printColor(0, 0, 0); 



    public System.Drawing.Drawing2D.DashStyle styleLine { get; set; } 
    public int widht=2; 

    /*=================================FILL PARAMETERS=====================================*/ 
    public printColor fillColorRGB = new printColor(255,255, 255); 
    public shape() 
    { 
    } 

    protected shape(SerializationInfo info, StreamingContext context) 
    { 
     colorRGB.r = info.GetInt32("colorLine.r"); 
     colorRGB.g = info.GetInt32("colorLine.g"); 
     colorRGB.b = info.GetInt32("colorLine.b"); 
     borderStyle = info.GetInt32("borderStyle"); 
     fillColorRGB.r = info.GetInt32("fillColorRGB.r"); 
     fillColorRGB.g = info.GetInt32("fillColorRGB.g"); 
     fillColorRGB.b = info.GetInt32("fillColorRGB.b"); 
     widht = info.GetInt32("widht"); 

    } 

    public virtual void GetObjectData(SerializationInfo info, StreamingContext context) 
    { 
     info.AddValue("colorLine.r",colorRGB.r); 
     info.AddValue("colorLine.g", colorRGB.g); 
     info.AddValue("colorLine.b", colorRGB.b); 
     info.AddValue("borderStyle",borderStyle); 
     info.AddValue("fillColorRGB.r", fillColorRGB.r); 
     info.AddValue("fillColorRGB.g", fillColorRGB.g); 
     info.AddValue("fillColorRGB.b", fillColorRGB.b); 
     info.AddValue("widht", widht); 
    } 
..... 

1.我是如何序列化的結構像

[Serializable] 
public struct CoOrds 

類之下，如何放它形狀和GetObjectData，因爲我有太多的類，我必須使用此結構

Thx

Answer 1

您可以直接使用info.AddValue("Pos", pos, typeof(CoOrds)將其序列化，也可以將其轉換爲string。

[Serializable()] 
public struct Coords 
{ 
    readonly public double x, y, z; 

    public Coords(double x, double y, double z) 
    { 
     this.x = x; 
     this.y = y; 
     this.z = z; 
    } 

    public static Coords FromString(string value) 
    { 
     if (string.IsNullOrEmpty(value)) return new Coords(); 
     double x = 0,y= 0,z = 0; 
     string[] parts = value.Split(','); 
     if (parts.Length > 0) double.TryParse(parts[0], out x); 
     if (parts.Length > 1) double.TryParse(parts[1], out y); 
     if (parts.Length > 2) double.TryParse(parts[2], out z); 
     return new Coords(x, y, z); 
    } 

    public override string ToString() 
    { 
     //Ensure round-trip formatting 
     return string.Format("{0:R},{1:R},{2:R}", x, y, z); 
    } 

} 

，然後用

[Serializable()] 
public class Vertex : ISerializable 
{ 
    public Coords pos1, pos2; 
    ... 
    public void GetObjectData(SerializationInfo info, StreamingContext context) 
    { 
     info.AddValue("Pos1", pos1.ToString()); 
     info.AddValue("Pos2", pos2, typeof(Coords)); 
    } 
    public Vertex(SerializationInfo info, StreamingContext context) 
    { 
     this.pos1 = Coords.FromString(info.GetValue("Pos1", typeof(string)) as string); 
     this.pos2 = (Coords)info.GetValue("Pos2", typeof(Coords)); 
    } 
} 

隨着工作同樣與測試代碼，我做了序列化。
