[C#] XMLWriter Encoding Issue / XMLWriter 控制文字編碼
December 26th, 2011 Phanix一般狀況下，如果不是很在意使用 XMLWriter 後輸出的文字編碼是哪一種的話，可以很簡單地用下面的方式完成
StringBuilder sb = new StringBuilder();
XmlWriter writer = XmlWriter.Create(sb);writer.WriteStartDocument();
//補上 xml 內容, 用 writer.WriteStartElement() 等完成
writer.WriteEndDocument();writer.Flush();
XmlDocument xmlDocument = new XmlDocument();
xmlDocument.LoadXml(sb.ToString());
但是可以發現到這樣子所輸出的 XML 文件是變成 UTF-16 encoding。雖然有 XmlWriterSettings 這東西可以去設定 XMLWriter 的編碼，不過看起來好像是有些問題，輸出的 XML 結果依舊是 UTF-16。
解決的方法是用 MemoryStream 與 XMLTextWriter。
MemoryStream stream = new MemoryStream();
XmlWriter writer = new XmlTextWriter(stream, Encoding.UTF8);writer.WriteStartDocument();
//補上 xml 內容, 用 writer.WriteStartElement() 等完成
writer.WriteEndDocument();writer.Flush();
StreamReader reader = new StreamReader(stream, Encoding.UTF8, true);
stream.Seek(0, SeekOrigin.Begin);
string result = reader.ReadToEnd();XmlDocument xmlDocument = new XmlDocument();
xmlDocument.LoadXml(result);

C# 處理 facebook JSON Serialized Data
July 19th, 2011 Phanix當透過 access token 去 facebook 抓取資料時，回傳的資料將以 JSON 的方式編碼，在 C# 裡頭可以用 JavaScriptSerializer 來處理，下面是個很懶惰的處理方式，不需要另外先去設計與宣告一個符合 facebook JSON 格式的 class object 來儲存資料，反正需要的時候再來針對 Key 另外處理即可。
.NET 取得 windows 帳號資訊
June 20th, 2011 Phanix取得登入帳號
Environment.UserName
取得帳號等有儲存在本機上的資訊
using System.Security.Principal;
using System.Threading;
//-----
AppDomain.CurrentDomain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);
WindowsPrincipal myPrincipal = (WindowsPrincipal)Thread.CurrentPrincipal;
WindowsIdentity myIdentity = (WindowsIdentity)myPrincipal.Identity;
Console.WriteLine("IdentityType: " + myIdentity.ToString());
Console.WriteLine("Name: {0}", myIdentity.Name);
Console.WriteLine("Member of Users? {0}", myPrincipal.IsInRole(WindowsBuiltInRole.User));
Console.WriteLine("Member of Administrators? {0}", myPrincipal.IsInRole(WindowsBuiltInRole.Administrator));
Console.WriteLine("Authenticated: {0}", myIdentity.IsAuthenticated);
Console.WriteLine("Anonymous: {0}", myIdentity.IsAnonymous);
取得帳號等有儲存在本機上的資訊 – II
使用 Win32 API
using System.Runtime.InteropServices;
//-----
[DllImport("Advapi32.dll", EntryPoint="GetUserName", ExactSpelling=false, SetLastError=true)]
static extern bool GetUserName([MarshalAs(UnmanagedType.LPArray)] byte[] lpBuffer,
[MarshalAs(UnmanagedType.LPArray)] Int32[] nSize );
//-----
byte[] str = new byte[256];
Int32[] len = new Int32[1];
len[0] = 256;
GetUserName(str, len);
MessageBox.Show(System.Text.Encoding.ASCII.GetString(str));
string a = System.Security.Principal.WindowsIdentity.GetCurrent().Name.ToString();
MessageBox.Show(a.ToString());
LDAP
這是可以取得最詳細資訊的方法
using System.DirectoryServices;
//-----
string principal = Environment.UserName;
string filter = string.Format("(&(ObjectClass={0})(sAMAccountName={1}))", "person", principal);
string[] properties = new string[] { "fullname" };
//用匿名登入，理論上LDAP都會允許，但只有 read 權限
DirectoryEntry adRoot = new DirectoryEntry("LDAP://yourdomain.com", null, null, AuthenticationTypes.Secure);
DirectorySearcher searcher = new DirectorySearcher(adRoot);
searcher.SearchScope = SearchScope.Subtree;
searcher.ReferralChasing = ReferralChasingOption.All;
searcher.PropertiesToLoad.AddRange(properties);
searcher.Filter = filter;
SearchResult result = searcher.FindOne();
DirectoryEntry directoryEntry = result.GetDirectoryEntry();
string displayName = directoryEntry.Properties["displayName"][0].ToString();
string firstName = directoryEntry.Properties["givenName"][0].ToString();
string lastName = directoryEntry.Properties["sn"][0].ToString();
string email = directoryEntry.Properties["mail"][0].ToString();
string department = directoryEntry.Properties["department"][0].ToString();
string description = directoryEntry.Properties["description"][0].ToString();

At the beginning, I hope to scrounge the solution from Internet, but after hours of searching, I only find some possible hints. Anyway, here’s the solution.
