c#中结构的转化示例:
structconversion.cs using System; struct RomanNumeral { public RomanNumeral(int value) { this.value = value; } static public implicit operator RomanNumeral(int value) { return new RomanNumeral(value); } static public implicit operator RomanNumeral(BinaryNumeral binary) { return new RomanNumeral((int)binary); } static public explicit operator int(RomanNumeral roman) { return roman.value; } static public implicit operator string(RomanNumeral roman) { return("Conversion not yet implemented"; } private int value; } struct BinaryNumeral { public BinaryNumeral(int value) { this.value = value; } static public implicit operator BinaryNumeral(int value) { return new BinaryNumeral(value); } static public implicit operator string(BinaryNumeral binary) { return("Conversion not yet implemented"; } static public explicit operator int(BinaryNumeral binary) { return(binary.value); } private int value; } class Test { static public void Main() { RomanNumeral roman; roman = 10; BinaryNumeral binary; // Perform a conversion from a RomanNumeral to a // BinaryNumeral: binary = (BinaryNumeral)(int)roman; // Performs a conversion from a BinaryNumeral to a RomanNumeral. // No cast is required: roman = binary; Console.WriteLine((int)binary); Console.WriteLine(binary); } }
