阵列中的结构C＃ [英] array in struct C#

问题描述

我以前的问题，阵列中的C＃。我在C＃很新我已经习惯了在Java中做节目。 我想从C ++转让本code到C＃。 这是code在C ++

I 've problem with array in C#. I'm quite new in C# I'm used to do programs in java. I'm trying to transfer this code from C++ to C#. This is code in C++

typedef struct point_3d {           // Structure for a 3-dimensional point (NEW)
    double x, y, z;
} POINT_3D;

typedef struct bpatch {             // Structure for a 3rd degree bezier patch (NEW)
    POINT_3D    anchors[4][4];          // 4x4 grid of anchor points
    GLuint      dlBPatch;               // Display List for Bezier Patch
    GLuint      texture;                // Texture for the patch
} BEZIER_PATCH;

我在C＃这就是浮存X，Y，Z结构体Vector3类型（我不需要双...） 现在，我努力使结构bpatch和我有问题数组的声明

I have struct Vector3 in C# which is float x,y,z (I don't need double ...) Now I'm trying to make structure bpatch and I have problems with the declaration of array

[StructLayout(LayoutKind.Sequential)]
struct BPatch
{
  Vector3[][] anchors = new Vector3[4][4]; //there is the problem
  uint dblPatch; // I'll probably have to change this two lines but it doesn't matter now
  uint texture; 

}

我该怎么办错了？我需要在结构上阿雷四轮驱动，它的类型应该是被声明为float X，浮动Y，浮动ž结构Vector3类型。 谢谢

what do I do wrong?? I need aray 4x4 in structure, its type should be structure Vector3 which is declared as float x, float y, float z. Thanks

推荐答案

在C＃中，Vector3类型[] []不是矩阵而是一个数组的数组。所以，你需要这样做：

In C#, Vector3[][] is not a matrix but an array of arrays. So, you will need to do this:

anchors = new Vector3[4][];
for(var i=0;i<anchors.Length;i++)
    anchors[i] = new Vector3[4];

下面是从MSDN http://msdn.microsoft.com/en一些文档-us /库/ 2s05feca.aspx

另一种方式，内嵌：

Vector3[][] anchors = new Vector3[][]{new Vector3[4],new Vector3[4],new Vector3[4],new Vector3[4]};

希望它帮助。
