示例以逗号分隔的同一组合框中显示所选项目.

但是当我尝试在wpfform中使用Usercontrol时,我得到了这个异常

我有一个测试wcf服务与默认方法和Web配置是:

在本地IIS上,当我发布它时工作正常.但是当我尝试在远程IIS上发布时,我收到此错误:

我正在研究cookies.我可以很容易地创建cookie.要创建cookie,我使用此代码:

HttpCookie aCookie = new HttpCookie("Cookie name");
aCookie.Value = "Value";
Response.Cookies.Add(aCookie); 

这段代码对我来说很好,它给了我localhost作为主机.但是,当我尝试在此处添加域名时问题就出现了:

HttpCookie aCookie = new HttpCookie("Cookie name");
aCookie.Value = "Value";
aCookie.Domain = "192.168.0.11";
Response.Cookies.Add(aCookie); 

现在没有生成cookie.有什么建议？

我正在处理一个应用程序一切正常,但我得到例外

这是我生成此异常的代码.

我正在使用以下命令创建证书，该证书将在窗口应用程序中使用。我们需要此证书来验证 cyberark 安全工具的应用程序。

New-SelfSignedCertificate -DnsName "www.companyname.com", "www.companyname.com" -CertStoreLocatio "cert:\LocalMachine\My" -Type "CodeSigningCert" -Subject "Application Name" -KeyUsage "DigitalSignature"

通过使用上面的命令，我可以创建证书。

问题：

1.当我查看已安装的证书时，它显示：

2.也只显示一年有效日期。如何将有效日期范围增加一年以上。
