可訪問性不一致：參數類型不是方法與WCF MEX

Question

我在做作業不太容易接近，我得到這個錯誤：

Error 1 Inconsistent accessibility: parameter type 'MexWcfService.MyComplex' is less accessible than method 'MexWcfService.Calculator.complex_sum(MexWcfService.MyComplex, MexWcfService.MyComplex)' E:\North Central College\CSC615\lab8\MexWcfService\MexWcfService\Program.cs 75 26 MexWcfService

下面是我的代碼。我的問題發生在..公共MyComplex complex_sum（MyComplex a，MyComplex b）的接口實現類中...

有人可以幫我解決這個問題。我對C＃很陌生，更不用說帶有元數據交換端點的WCF了。任何指針將不勝感激。

Answer 1

您需要將類MyComplex聲明爲public，因爲您已經在類Calculator中使用公共方法中的類型。

Answer 2

我有類似的問題，而傳遞值作爲參數。我使參數類型的訪問說明符與方法訪問說明符相同。
