问题描述

这是新版本的4.0版，被称为动态版。告诉我我在代码中可以使用的方式，以及这个未来可以帮助我吗？

相关问题： p>

• 新的动态C＃4.0关键字是否废弃var关键字？


• 您认为新的C＃4.0动态关键字是什么？

解决方案

我们在TDD中使用C＃dynamic关键字。

此代码不会编译，因为方法Addition未实现

  [TestMethod ）] 
 public void CalculatorThingAdd_2PositiveNumbers_ResultAdded（）
 {
 CalculatorThing myCalculator = new CalculatorThing（）; 
 int result = 0; 
 int expcected = 3; 
 
 //  - > CalculatorThing不包含'Addition'的定义
 result = myCalculator.Addition（1，2）; 
 
 Assert.AreEqual（result，expcected）; 
} 
  

使用动态关键字代码编译，测试失败！ - > TDD

解决方案

We use the C# "dynamic" keyword with TDD.

This code doesn't compile because the method "Addition" is not implemented

[TestMethod()]
public void CalculatorThingAdd_2PositiveNumbers_ResultAdded()
{
    CalculatorThing myCalculator = new CalculatorThing();
    int result = 0; 
    int expcected = 3;

    // --> CalculatorThing  does not contain a definition for 'Addition'
    result = myCalculator.Addition(1, 2);

    Assert.AreEqual(result, expcected);
}

With the "dynamic" keyword the code compiles and the test fails! --> TDD
