parameters - 我该如何解决这个Moq错误？ System.Reflection.TargetParameterCountException : Parameter count mismatch

Question

我在nUnit测试用例中使用Moq。

这是我的测试用例:

        IList<ChartFieldDepartment> coaDepartments = new List<ChartFieldDepartment>() {
                new ChartFieldDepartment { ChartFieldKey="1000", Description="Corporate Allocation"},
                new ChartFieldDepartment { ChartFieldKey="1010", Description="Contribution to Capital"}
        };

        Mock<IChartFieldRepository> mockChartFieldRepository = new Mock<IChartFieldRepository>();
        mockChartFieldRepository.Setup(x => x.RetrieveChartFieldDepartments(It.IsAny<bool>())).Returns(coaDepartments.AsQueryable);

        ChartFieldDomainService chartFieldDomainService = new ChartFieldDomainService(mockChartFieldRepository.Object);

        // this line fails! I get System.Reflection.TargetParameterCountException : Parameter count mismatch
        IQueryable<ChartFieldDepartment> departments = chartFieldDomainService.RetrieveChartFieldDepartments();

这是我的 ChartFieldDomainService:

public class ChartFieldDomainService : IChartFieldDomainService
{
    private IChartFieldRepository _chartFieldRepository = null;

    public ChartFieldDomainService(IChartFieldRepository repository)
    {
        _chartFieldRepository = repository;
    }

    public virtual IQueryable<ChartFieldDepartment> RetrieveChartFieldDepartments()
    {
        return _chartFieldRepository.RetrieveChartFieldDepartments(true); // always refresh, get latest
    }
    //....
 }

先谢谢您的帮助。

编辑:解决方案

以下语法更改解决了该问题。

原始行:

        mockChartFieldRepository.Setup(x => x.RetrieveChartFieldDepartments(It.IsAny<bool>()))
            .Returns(coaDepartments.AsQueryable());

更新的行:

        mockChartFieldRepository.Setup(x => x.RetrieveChartFieldDepartments(It.IsAny<bool>()))
            .Returns((bool x) => coaDepartments.AsQueryable());

更改为

.Returns(coaDepartments.AsQueryable());

(从错误消息中根本看不出来。)
