19 阅读1分钟

在F#中,Static是一个关键词。用于制作static字段或static方法。static不是Object的一部分。它有自己的存储空间来存储static数据。它用于在对象之间共享公共属性。

F# Static示例1

type Account(accno,name) = class
 static let rateOfInterest = 8.8
 member this.display()=
  printfn "%d %s %0.2f" accno name rateOfInterest 

end let a1 = new Account(101,"Rajkumar") let a2 = new Account(102, "john") a1.display() a2.display()

输出:

101 Rajkumar 8.80
102 john 8.80

F# Static字段示例2

type Account() = class  
 static let mutable count = 0  
 new(accno,name) =    
  count<-count+1  
  printfn "%d %s" accno name  
  Account()  
 static member DisplayCount() = printfn "Object Counter = %d" count  

end
let a1 = new Account(101,"Rajkumar")
let a2 = new Account(102, "john")
Account.DisplayCount()

输出:

101 Rajkumar
102 john
Object Counter = 2
