座標上PictureBox的Image

Question

畫我想畫的圖片框和我的代碼如下：

List<IntPoint> edgePoints; 
List<IntPoint> corners; 

AForge.Imaging.Blob[] blobs = blobCounter.GetObjectsInformation(); 
Graphics g = Graphics.FromImage(pictureBox2.Image); 
Pen bluePen = new Pen(Color.Blue, 5); 

double[] blobAdjustedSize = new double[blobs.Length]; 
for (int i = 0, n = blobs.Length; i < n; i++) 
{ 
    edgePoints = blobCounter.GetBlobsEdgePoints(blobs[i]); 
    corners = PointsCloud.FindQuadrilateralCorners(edgePoints); 

    g.DrawPolygon(bluePen, corners); // **UNDERLINE** 
}   

而且我得到一個錯誤。下劃線爲g.DrawPolygon(bluePen, corners)。

錯誤是：

爲System.Drawing.Graphics.DrawPolygon最好重載的方法匹配（System.Drawing.Pen來，System.Drawing.Point []）」有一些無效參數

Answer 1

該公司預計的Array of Points，而不是一個列表，定義邊角爲Array或添加

using System.Linq; 

到文件的頂部，並將該行更改爲

g.DrawPolygon(bluePen, corners.ToArray());
