根据行数列数左上角右上角右下角算出矩阵所有坐标及间距，要求C Shap语言封装

以下是一个C#语言的矩阵坐标计算类的封装示例：

public class MatrixCoordinates
{
    private int rows;
    private int columns;
    private int startX;
    private int startY;
    private int endX;
    private int endY;
    private int width;
    private int height;

    public MatrixCoordinates(int rows, int columns, int startX, int startY, int endX, int endY)
    {
        this.rows = rows;
        this.columns = columns;
        this.startX = startX;
        this.startY = startY;
        this.endX = endX;
        this.endY = endY;

        this.width = (endX - startX) / (columns - 1);
        this.height = (endY - startY) / (rows - 1);
    }

    public List<Point> GetAllCoordinates()
    {
        List<Point> coordinates = new List<Point>();

        for (int i = 0; i < rows; i++)
        {
            for (int j = 0; j < columns; j++)
            {
                int x = startX + j * width;
                int y = startY + i * height;

                coordinates.Add(new Point(x, y));
            }
        }

        return coordinates;
    }

    public int GetWidth()
    {
        return width;
    }

    public int GetHeight()
    {
        return height;
    }
}

使用示例：

MatrixCoordinates mc = new MatrixCoordinates(3, 4, 0, 0, 100, 100);
List<Point> coordinates = mc.GetAllCoordinates();

foreach (Point p in coordinates)
{
    Console.WriteLine("X: " + p.X + ", Y: " + p.Y);
}

Console.WriteLine("Width: " + mc.GetWidth() + ", Height: " + mc.GetHeight());

该示例中创建了一个3行4列的矩阵，左上角坐标为(0,0)，右下角坐标为(100,100)，然后通过调用GetAllCoordinates方法获取了所有坐标，最后通过GetWidth和GetHeight方法获取了矩阵中每个元素之间的宽度和高度。
