從F調用C＃

Question

任何任何從f＃代碼調用c＃函數的想法。

我有像這樣

public class VehicleDetailsBridge 
{ 

    public void SaveVehicle(long id) 
    { 
     var db = "test call"; 
    } 
} 

一個C＃函數，那麼F＃中，我有：

type Persistence as this = 
    member x.SaveToDatabase(LatestVid) 
    let b = VehicleDetailsBridge() 
    b.SaveVehicle(LatestVid) 

我在F＃項目C＃類庫的引用。

然而，當我運行這段代碼我得到以下例外Xamarin：

Mono.Debugger.Soft.VMDisconnectedExecption

Answer 1

試試這個：

let b = VehicleDetailsBridge() // create instance of class 
b.SaveVehicle(LatestVid) 

VehicleDetailsBridge是所以你需要打開這個課程。

Answer 2

type Persistence() =       // need braces here, and not 'as this' 
    member x.SaveToDatabase(latestVid) = 
     let b = VehicleDetailsBridge()  // indent the method body 
     b.SaveVehicle(latestVid) 

我的全F＃程序如下：

open FsCsInterop 

type Persistence() =       // need braces here, and not 'as this' 
    member x.SaveToDatabase(latestVid) = 
     let b = VehicleDetailsBridge()  // indent the method body 
     b.SaveVehicle(latestVid) 
     printfn "Saved %d" latestVid 

[<EntryPoint>] 
let main argv = 
    let p = Persistence() 
    p.SaveToDatabase(2L) 
    0 

// Prints "Saved 2"
