本文实例讲述了C#显式地实现接口成员的方法。分享给大家供大家参考。具体实现方法如下：

// explicit1.csinterface IDimensions { float Length(); float Width();}class Box : IDimensions { float lengthInches; float widthInches; public Box(float length, float width) { lengthInches = length; widthInches = width; } // 显式接口成员实现： float IDimensions.Length() { return lengthInches; } // 显式接口成员实现： float IDimensions.Width() { return widthInches; } public static void Main() { // 声明类实例“myBox”： Box myBox = new Box(30.0f, 20.0f); // 声明接口实例“myDimensions”： IDimensions myDimensions = (IDimensions) myBox; // 打印出盒子的尺寸： //System.Console.WriteLine("Length: {0}", myBox.Length()); //System.Console.WriteLine("Width: {0}", myBox.Width()); System.Console.WriteLine("Length: {0}", myDimensions.Length()); System.Console.WriteLine("Width: {0}", myDimensions.Width()); }}

代码2：

// explicit2.cs// 声明英制单位接口：interface IEnglishDimensions{ float Length(); float Width();}// 声明公制单位接口：interface IMetricDimensions{ float Length(); float Width();}// 声明实现以下两个接口的“Box”类：// IEnglishDimensions 和 IMetricDimensions：class Box : IEnglishDimensions, IMetricDimensions{ float lengthInches; float widthInches; public Box(float length, float width) { lengthInches = length; widthInches = width; }// 显式实现 IEnglishDimensions 的成员： float IEnglishDimensions.Length() { return lengthInches; } float IEnglishDimensions.Width() { return widthInches; }// 显式实现 IMetricDimensions 的成员： float IMetricDimensions.Length() { return lengthInches * 2.54f; } float IMetricDimensions.Width() { return widthInches * 2.54f; } public static void Main() { // 声明类实例“myBox”： Box myBox = new Box(30.0f, 20.0f); // 声明英制单位接口的实例： IEnglishDimensions eDimensions = (IEnglishDimensions) myBox; // 声明公制单位接口的实例： IMetricDimensions mDimensions = (IMetricDimensions) myBox; // 以英制单位打印尺寸： System.Console.WriteLine("Length(in): {0}", eDimensions.Length()); System.Console.WriteLine("Width (in): {0}", eDimensions.Width()); // 以公制单位打印尺寸： System.Console.WriteLine("Length(cm): {0}", mDimensions.Length()); System.Console.WriteLine("Width (cm): {0}", mDimensions.Width()); }}

希望本文所述对大家的C#程序设计有所帮助。
