从vb.net将MOQ设置代码转换为c#

Question

我在c#中有一个表达式og (lambda/linq)。当试图在vb.net中使用这段代码时，我会得到一个错误

C#代码

_dataLayerMock.Setup(x => x.SaveAccount(It.Is<Account>(a => a.AccountType == AccountType.Private)));  

转换的VB.net代码

_dataLayerMock.Setup(Function(x) x.SaveAccount(It.[Is](Of Account)(Function(a) a.AccountType = AccountType.[Private])))

误差

Error   1   Overload resolution failed because no accessible 'Setup' can be called with these arguments:
    'Public Function Setup(Of TResult)(expression As System.Linq.Expressions.Expression(Of System.Func(Of ConsoleApplication1.IDataLayer, TResult))) As Moq.Language.Flow.ISetup(Of ConsoleApplication1.IDataLayer, TResult)': Expression does not produce a value.
    'Public Function Setup(Of TResult)(expression As System.Linq.Expressions.Expression(Of System.Func(Of ConsoleApplication1.IDataLayer, TResult))) As Moq.Language.Flow.ISetup(Of ConsoleApplication1.IDataLayer, TResult)': Data type(s) of the type parameter(s) cannot be inferred from these arguments. Specifying the data type(s) explicitly might correct this error.
    'Public Function Setup(expression As System.Linq.Expressions.Expression(Of System.Action(Of ConsoleApplication1.IDataLayer))) As Moq.Language.Flow.ISetup(Of ConsoleApplication1.IDataLayer)': Expression does not produce a value. D:\Araamudhan\Project\Amex\Maven-NPanday\Application\ClassLibrary\LinqTest\LinqTest\BusinessLayerTest.vb    20  9   LinqTest

有人能帮我解决这个问题吗？

Answer 1

使用代码转换器之一--它们对这些实例非常有用。http://converter.telerik.com/

_dataLayerMock.Setup(Function(x) x.SaveAccount(It.[Is](Function(a) a.AccountType = AccountType.[Private])))

你可能不再需要这个答案了，但万一其他人遇到这个问题。

我认为这在VB.net中行不通，因为lambda必须在vb中返回一个值，因此不允许您在VB中模拟子方法。

希望这能有所帮助
