为什么此参数不符合CLS？

Question

我试图消除我们在整个解决方案中遇到的所有符合CLS的错误.虽然我已经设法排序了几个(例如以下划线开头并使用无符号整数的公共变量),但有一些我似乎无法找到它们失败的原因.

我已经粘贴了与其中一个问题相关的所有代码,有相当数量的代码,但它只包含一个表单构造函数,接口和实现该接口的类.

VB.Net表单构造函数(警告在unitOfWork参数上并且读取参数类型'unitOfWork'不符合CLS:

Public Sub New(ByRef unitOfWork As IUnitOfWork)

    MyBase.New()
    InitializeComponent()

    _unitOfWork = unitOfWork

End Sub

界面IUnitOfWork如下:

public interface IUnitOfWork : IDisposable
{
    bool IsInTransaction { get; }

    bool IsDirty { get; }

    object BeginTransaction();

    object BeginTransaction(IsolationLevel isolationLevel);

    void Commit();

    void Rollback();

    object Session { get; }
}

接口的唯一实现(因此其实例将传递给表单构造函数)是这样的:

public class UnitOfWork : IUnitOfWork
{
    private ISession _session;

    public UnitOfWork(SMSession session)
    {
        if (session == null)
        {
            throw new ArgumentNullException("Session wasn't supplied");
        }

        this._session = (ISession)session.OpenSession();
    }

    public bool IsInTransaction
    {
        get { return this._session.Transaction.IsActive; }
    }

    public bool IsDirty
    {
        get { return this._session.IsDirty(); }
    }

    public object Session
    {
        get { return this._session; }
    }

    public object BeginTransaction() 
    {
        return this._session.BeginTransaction(IsolationLevel.ReadCommitted);
    }

    public object BeginTransaction(IsolationLevel isolationLevel) 
    {
        return this._session.BeginTransaction(isolationLevel);
    }

    public void Commit()
    {
        if (this._session.Transaction == null)
        {
            throw new NullReferenceException
                ("The Transaction has not been initialised");
        }

        this._session.Transaction.Commit();
    }

    public void Rollback()
    {
        if (this._session.Transaction == null)
        {
            throw new NullReferenceException
                ("The Transaction has not been initialised");
        }

        this._session.Transaction.Rollback();
    }

    private bool disposed = false;

    protected virtual void Dispose(bool disposing)
    {
        if (!this.disposed)
        {
            if (disposing)
            {
                this._session.Dispose();
            }
        }
        this.disposed = true;
    }

    public void Dispose()
    {
        if (this._session != null)
        {
            this._session.Dispose();
        }

        Dispose(true);
        GC.SuppressFinalize(this);
    }
}

我要么对这个问题视而不见(可能是因为我多年来一直盯着这个问题!)或者还有另一个我不知道的CLS合规限制.有什么建议？

我的猜测是你的C#库本身没有用CLSCompliant标记.我刚刚复制了错误,VB项目标记为CLSCompliant,它引用的C#库未标记为CLSCompliant.

我标记了C#库CLSCompliant,警告消失了.
