예제

다음 예제에서는 여러 메서드에서 반복되는 코드 계약의 약어 이름을 만드는 방법을 보여 줍니다.

using System.Diagnostics.Contracts;

{  
   public int State { get; }  
   public int Data { get; }  

   [ ContractAbbreviator ]

   {  
      Contract.Ensures( this .State == Contract.OldValue(this.State));  
      Contract.Ensures( this .Data == Contract.OldValue(this.Data));  
   }  

   [ ContractAbbreviator ]  
   private void InStateZeroAndUnchanged()   
   {  
      Contract.Requires( this.State == 0);  
      DataAndStateUnchanged();  
   }  

   public void Method1(...)
