using IronSoftware.Drawing; using System; PointF pointFloat = new PointF(22.2f, 25.7f); int hashCode = pointFloat.GetHashCode(); // Output hash code value of this point Console.WriteLine(hashCode);

获取哈希代码

Another method available in the Point and PointF classes in IronDrawing is the GetHashCode() method. A hash code is a numerical value that represents the identity of an object in a unique way, such as a Point. Hash codes are typically used in dictionaries, hash sets, and hash tables to facilitate object equality and hashing operations.

To obtain the hash code of a Point, simply call the GetHashCode() method on an instantiated Point or PointF object. The method returns a System.Int32 object which can be printed or stored.

Both the GetHashCode() and Equals() methods can be used to compare the equality of two points. However, the Equals() method provides direct results for equality checks, whereas the GetHashCode() method is mainly used to obtain the hash code of a point, which is then used in data structures like dictionaries or hash tables.
