                {
                    this.progressBar.Owner.Invoke(delegate
                    {
                        this.progressBar.PerformStep();
                    }
                    );
                    return;

}

推荐答案

尝试一下:

Try this:

public virtual void Step()
        {
            if (this.progressBar != null)
            {
                if (this.progressBar.Owner == null)
                {
                    return;
                }
                if (this.progressBar.Owner.InvokeRequired)
                {
                    this.progressBar.Owner.Invoke(new MethodInvoker( delegate{ Step();}));
                    return;
                }
                this.progressBar.PerformStep();
            }
        }
    }
}
