一条线被分割成多段，计算线段所有顶点的坐标，C#代码

以下是将线段分割成多段后计算所有顶点坐标的C#代码示例：

// 定义线段起点和终点的坐标
int startX = 0;
int startY = 0;
int endX = 20;
int endY = 10;

// 定义要分割的段数
int segmentCount = 5;

// 计算每段的长度
int segmentLength = (int)Math.Round(Math.Sqrt(Math.Pow(endX - startX, 2) + Math.Pow(endY - startY, 2)) / segmentCount);

// 定义变量保存当前顶点的坐标
int currentX = startX;
int currentY = startY;

// 计算所有顶点的坐标
for (int i = 1; i <= segmentCount; i++)
{
    // 计算当前段的终点坐标
    int segmentEndX = startX + (endX - startX) * i / segmentCount;
    int segmentEndY = startY + (endY - startY) * i / segmentCount;
    
    // 在当前段内按照段长计算顶点坐标
    while (currentX < segmentEndX || currentY < segmentEndY)
    {
        Console.WriteLine("({0},{1})", currentX, currentY);
        
        int deltaX = segmentEndX - currentX;
        int deltaY = segmentEndY - currentY;
        double length = Math.Sqrt(deltaX * deltaX + deltaY * deltaY);
        double ratio = segmentLength / length;
        
        currentX = (int)Math.Round(currentX + ratio * deltaX);
        currentY = (int)Math.Round(currentY + ratio * deltaY);
    }
}

// 输出终点坐标
Console.WriteLine("({0},{1})", endX, endY);

以上代码将线段起点和终点的坐标设为(0,0)和(20,10)，将线段分割成5段后，计算所有顶点的坐标并输出。你可以根据实际情况修改代码中的坐标值和分割的段数。
