首先在linux上推荐用途：%LocalApplicationData%

ENM: System.Environment.SpecialFolder.LocalApplicationData
WIN: C:\Users\USER\AppData\Local
LIN: /home/USER/.local/share
OSX: /Users/USER/.local/share

如果你以超级用户/root/.local/share的身份运行它，路径就是。
如果以普通用户/home/victor/.local/share的身份运行
如果你想看到一个特殊文件夹的路径，使用这个：

Console.WriteLine("My folder: " + Environment.GetFolderPath( Environment.SpecialFolder.LocalApplicationData));

超级用户路径：

普通用户路径：

这可能有助于您找到文件夹。
由于我运行的程序作为超级用户，它是在（用户）-〉root/.local/share * 您只能访问此文件夹时，登录为根 *

以下是普通用户的另一个：

我的Securityconfiguration（我做了一个客户端，但我猜它和服务器几乎一样）：

SecurityConfiguration = new SecurityConfiguration
            {
                ApplicationCertificate = new CertificateIdentifier { StoreType = @"Directory", StorePath = @"%LocalApplicationData%/OPCFoundation/CertificateStores/MachineDefault", SubjectName = "Mything" },
                TrustedIssuerCertificates = new CertificateTrustList { StoreType = @"Directory", StorePath = @"%LocalApplicationData%/OPCFoundation/CertificateStores/UA Certificate Authorities" },
                TrustedPeerCertificates = new CertificateTrustList { StoreType = @"Directory", StorePath = @"%LocalApplicationData%/OPCFoundation/CertificateStores/UA Applications" },
                RejectedCertificateStore = new CertificateTrustList { StoreType = @"Directory", StorePath = @"%LocalApplicationData%/OPCFoundation/CertificateStores/RejectedCertificates" },
                AutoAcceptUntrustedCertificates = true
            },
