我已经查看了这些帖子: wcf System.ServiceModel.AddressAlreadyInUseException, Windows Service通过HTTPS托管WCF, 升级到.NET 4.5后获取AddressAlreadyInUseException,它们都没有解决我的问题.我在.net 4.5中有几个wcf服务.所有这些都在同一个地址中,我在WCF服务主机中得到此异常:

我正在为Excel开发一个vsto插件，并且试图将颜色更改为Excel中的注释。

这是我的代码：

Excel.Range activeCell = _application.ActiveCell;
activeCell.AddComment("some text"));
activeCell.Comment.Shape.Fill.BackColor = Color.Red;

我得到的例外是：

无法将类型“ System.Drawing.Color”隐式转换为“ Microsoft.Office.Interop.Excel.ColorFormat”

我找不到如何在两种格式之间进行转换。
