C# 比较C中的System.Drawing.Drawing2D.GraphicPath#

我需要比较两个图形路径，以调查图形中是否有任何更改

我开始比较课程，但结果总是不符合我的预期

路径：

var path1 = CreateGraphicsPath(0, 0, 100, 100);
var path2 = CreateGraphicsPath(0, 0, 100, 100);

var path3 = CreateGraphicsPath(0, 0, 200, 200);
var path4 = path3.Clone() as GraphicsPath;

    path1.Equals(path2); // false
    path1 == path2;      // false

    path3.Equals(path4); // false (That was unexpected)
    path3 == path;       // false

    // PathData Comparision
    path1.PathData.Equals(path2.PathData);                            // false
    path1.PathData == path2.PathData;                                 // false

    // PathPoints Comparision
    path1.PathPoints.Equals(path2.PathPoints);                        // false
    path1.PathPoints == path2.PathPoints;                             // false

    // Hashcodes Comparision
    path1.GetHashCode() == path2.GetHashCode();                       // false
    path1.PathData.GetHashCode() == path2.PathData.GetHashCode();     // false
    path1.PathPoints.GetHashCode() == path2.PathPoints.GetHashCode(); // false

路径的创建：（在该示例中仅为矩形）

我的测试：

var path1 = CreateGraphicsPath(0, 0, 100, 100);
var path2 = CreateGraphicsPath(0, 0, 100, 100);

var path3 = CreateGraphicsPath(0, 0, 200, 200);
var path4 = path3.Clone() as GraphicsPath;

    path1.Equals(path2); // false
    path1 == path2;      // false

    path3.Equals(path4); // false (That was unexpected)
    path3 == path;       // false

    // PathData Comparision
    path1.PathData.Equals(path2.PathData);                            // false
    path1.PathData == path2.PathData;                                 // false

    // PathPoints Comparision
    path1.PathPoints.Equals(path2.PathPoints);                        // false
    path1.PathPoints == path2.PathPoints;                             // false

    // Hashcodes Comparision
    path1.GetHashCode() == path2.GetHashCode();                       // false
    path1.PathData.GetHashCode() == path2.PathData.GetHashCode();     // false
    path1.PathPoints.GetHashCode() == path2.PathPoints.GetHashCode(); // false

我也尝试过：

var path1 = CreateGraphicsPath(0, 0, 100, 100);
var path2 = CreateGraphicsPath(0, 0, 100, 100);

var path3 = CreateGraphicsPath(0, 0, 200, 200);
var path4 = path3.Clone() as GraphicsPath;

    path1.Equals(path2); // false
    path1 == path2;      // false

    path3.Equals(path4); // false (That was unexpected)
    path3 == path;       // false

    // PathData Comparision
    path1.PathData.Equals(path2.PathData);                            // false
    path1.PathData == path2.PathData;                                 // false

    // PathPoints Comparision
    path1.PathPoints.Equals(path2.PathPoints);                        // false
    path1.PathPoints == path2.PathPoints;                             // false

    // Hashcodes Comparision
    path1.GetHashCode() == path2.GetHashCode();                       // false
    path1.PathData.GetHashCode() == path2.PathData.GetHashCode();     // false
    path1.PathPoints.GetHashCode() == path2.PathPoints.GetHashCode(); // false

有什么我看不到的吗？ 这比我想象的要简单得多吗

谢谢你的建议：）
