C#类和结构

C#类和结构,c#,class,struct,serializable,C#,Class,Struct,Serializable,我对C中的序列化有一些问题# 拥有代码: 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 pr

我对C中的序列化有一些问题# 拥有代码:

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);
    }
 .....
一,。我怎样才能像序列化结构一样

[Serializable]
public struct CoOrds
在类下以及如何将其放入形状和GetObjectData中,因为我有太多的类必须使用此结构


Thx

您可以直接使用
info.AddValue(“Pos”,Pos,typeof(CoOrds)
对其进行序列化,或者您可以将其转换为
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);
    }

}
然后用

[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));
    }
}

与我所做的测试代码一样好。

您可以直接使用
info.AddValue(“Pos”,Pos,typeof(CoOrds)
对其进行序列化,或者您可以将其转换为/从
字符串

[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);
    }

}
然后用

[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));
    }
}

与测试代码一样,我做得很好。

@user1137147:我真的不理解你的问题。如果你将结构的内容保存在二进制序列化中,比如你使用的
colorline.R
?现在我想知道关于可序列化的问题,我现在可以这样做,但我必须这样做的代码太多了s可序列化,如果我能做得更简单,我会做的。可变结构是邪恶的。除非绝对必要,否则尽量避免使用它们。是否有什么原因必须实现
ISerializable
?是否将
struct
标记为
[serializable]
还是不?@user1137147:我真的不明白你的问题。如果你把结构的内容保存在二进制序列化中,比如你用
colorline.R
?现在我只想知道可序列化的问题。我现在可以这样做,但是我有太多的代码必须进行序列化,如果我可以轻松地完成的话我不知道,可变结构是邪恶的。除非绝对必要,否则尽量避免使用它们。你有什么理由必须实现
ISerializable

是否标记为

?ooooooo!这就是我搜索的,thxooo!这就是我搜索的,Thx
