Question

使用C＃MVC 5从搜索中的活动目录中提取数据。其中一个我需要它来拉缩略图照片。

所以我的LDAP连接抓取了初始数据，并成功地将缩略图转换为byte []，至少从调试看起来是这样。然后，当我尝试将字节数组转换为图像时，我得到一个＆＃34;参数无效＆＃34;错误。

这是我的控制器：

  [HttpPost]
public ActionResult Index(string userName, string searchFilter)
{
    /**********Establish Connection********/
    DirectoryEntry dir = createDirectoryEntry();
    DirectorySearcher search = new DirectorySearcher(dir);
    /****Refer to class constructor****/


    /********Create the List to store results in***************/
    List<ADUser> Users = new List<ADUser>();
    string DisplayName = "", SAMAccountName = "", Mail = "", Description = "", Department = "", TelephoneNumber = "", Fax = "";
    byte[] ThumbnailPhoto;
    string searchFilters = searchFilter.ToString();
    /*******Filter parameters************/
    if (searchFilters == "1")
    {
        search.Filter = "(&(objectCategory=Person)(objectClass=User)(&(anr=" + userName + "* )(displayName=*)(sn=*)))";
        //(&(department=" + userName + "* )(displayName=*)(sn=*))(&(telephoneNumber=" + userName + " )(displayName=*)(sn=*))
    }
    else if (searchFilters == "2")
    {
        search.Filter = "(&(objectCategory=Person)(objectClass=User)(&(department=" + userName + "* )(displayName=*)(sn=*)))";
    }
    else if (searchFilters == "3")
    {
        search.Filter = "(&(objectCategory=Person)(objectClass=User)(&(telephoneNumber=" + userName + "* )(displayName=*)(sn=*)))";

    return View();

我的构造函数：

public class ADUser
    {
        private string name;
        private string domainUserName;

        private string telephoneNumber;
        private string faxNumber;

        private byte[] thumbnailPhoto;

        public ADUser(string name, string domainUserName, string emailAddress, string jobDescription, string telephoneNumber, string faxNumber, string department, byte[] thumbnailPhoto)
        {
            this.name = name;
            this.domainUserName = domainUserName;
            this.emailAddress = emailAddress;
            this.jobDescription = jobDescription;
            this.telephoneNumber = telephoneNumber;
            this.faxNumber = faxNumber;
            this.department = department;
            this.thumbnailPhoto = thumbnailPhoto;
        }

        public string Name
        {
            get { return name; }
            set { name = value; }
        }

        public string DomainUserName
        {
            get { return domainUserName; }
            set { domainUserName = value; }
        }

        public string EmailAddress
        {
            get { return emailAddress; }
            set { emailAddress = value; }
        }

        public string JobDescription
        {
            get { return jobDescription; }
            set { jobDescription = value; }
        }

        public string TelephoneNumber
        {
            get { return telephoneNumber; }
            set { telephoneNumber = value; }
        }

        public string FaxNumber
        {

            set { faxNumber = value; }
        }

        public string Department
        {

            set { department = value; }
        }

        public byte[] ThumbnailPhoto
        {
            get { return thumbnailPhoto; }
            set { thumbnailPhoto = value; }
        }
