使用.Net核心检查目录是否具有读写权限

using System.IO;

string directoryPath = "目录路径";
if (Directory.Exists(directoryPath))
{
    // 目录存在
}
else
{
    // 目录不存在
}

DirectorySecurity directorySecurity = Directory.GetAccessControl(directoryPath);

AuthorizationRuleCollection accessRules = directorySecurity.GetAccessRules(true, true, typeof(System.Security.Principal.SecurityIdentifier));

bool hasReadWritePermission = false;
foreach (FileSystemAccessRule rule in accessRules)
{
    if (rule.FileSystemRights.HasFlag(FileSystemRights.Read) && rule.FileSystemRights.HasFlag(FileSystemRights.Write))
    {
        hasReadWritePermission = true;
        break;
    }
}

if (hasReadWritePermission)
{
    // 目录具有读写权限
}
else
{
    // 目录没有读写权限
}
