When serializing an XML file, an error occurs in the following manner: XmlSerializer serializer= new XmlSerializer(typeof(MyType)); Errors such as : The assembly with display name 'mscorlib.XmlSerializers' failed to load in the 'LoadFrom' binding context of the AppDomain with ID 1. The cause of the failure was: System.IO.FileNotFoundException: Could not load file or assembly 'mscorlib.XmlSerializers, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies.

Being of the email changes saved, then the execution of the mail Save () method, you may experience the error   "The operation can not be performed Because the message Has Been changed."  Especially if you go to edit multiple email. This is due to the object  Microsoft.Office.Interop.Outlook.UserProperty  that was not released.   So before the save is to be performed education System.Runtime.InteropServices.Marshal.ReleaseComObject (UserProperty). At this stage the previous post snippet becomes   public void AddCustomPropertyToMail (entryID string, string propertyName, string value) { Microsoft.Office.Interop.Outlook.MailItem mail = Globals.ThisAddIn.Application.Session.GetItemFromID (entryID) as Microsoft.Office.Interop.Outlook.MailItem; if (email! = Null) { Microsoft.Office.Interop.Outlook.UserProperty UserProperty = mail.UserProperties.Add (propertyName, Microsoft.Office.Interop.Outlook.OlUserPropertyType.olText); UserProperty.Val...

Use a double quote. ie @"this ""word"" is escaped";

This code will crop the image based on all white and transparent pixels from around the image public static Bitmap CropWhiteSpace(Bitmap bmp) { int w = bmp.Width; int h = bmp.Height; int white = 0xffffff; Func allWhiteRow = r => { for (int i = 0; i allWhiteColumn = c => { for (int i = 0; i = 0; --row) { if (!allWhiteRow(row)) break; bottommost = row; } int leftmost = 0, rightmost = 0; for (int col = 0; col = 0; --col) { if (!allWhiteColumn(col)) break; rightmost = col; } if (rightmost == 0) rightmost = w; // As reached left if (bottommost == 0) bottommost = h; // As reached top. int croppedWidth = rightmost - leftmost; int croppedHeight = bottommost - topmost; if (croppedWidth == 0) // No border on left or right { leftmost = 0; croppedWidth = w; } if (croppedHeight == 0) // No border on top or bottom { topmost = 0; croppedHeight = h; } try { var target = new Bi...

First, you have to check your ReportPath if is correct rpt.Load(Server.MapPath("crMembers.rpt"));

User Enum.Parse is your friend enum StatusEnum {Active,Inactive} StatusEnum MyStatus = (StatusEnum) Enum.Parse( typeof(StatusEnum), "Active");

You can use Like this Code private string ConvertUnicode(string Str) { Encoding latinEncoding = Encoding.GetEncoding("Windows-1252"); Encoding ArabicEncoding = Encoding.GetEncoding("Windows-1256"); byte[] latinBytes = latinEncoding.GetBytes(Str); return ArabicEncoding.GetString(latinBytes); }

Only letters: Regex.IsMatch(input, @"^[a-zA-Z]+$"); Only letters and numbers: Regex.IsMatch(input, @"^[a-zA-Z0-9]+$"); Only letters, numbers and underscore: Regex.IsMatch(input, @"^[a-zA-Z0-9_]+$");

To convert Date time by Format string datestring="12/2/2012"; DateTime.ParseExact(datestring, "MM/dd/yyyy", CultureInfo.InvariantCulture);

to get paraneter from url string Url = "http://localhost:6109/CANSHOP/GenerateCoupons.aspx?CouponId=1&MemberId=4"; Uri tempUri = new Uri(Url); string sQuery = tempUri.Query; var query = HttpUtility.ParseQueryString(sQuery); string cId = query["CouponId"]; string mId = query["MemberId"];

best way to convert "$10" to decimal is: decimal d = decimal.Parse("$45.00", NumberStyles.Currency); OR decimal.TryParse("$45.00", NumberStyles.Currency, culture, out d);

if you create a collection class that have a list of Class Like : public class Foo { public List BarList { get; set; } } public class Bar { public string Property1 { get; set; } public string Property2 { get; set; } } we can use XmlSerializer to Save Collection to XML File Foo f = new Foo(); f.BarList = new List (); f.BarList.Add(new Bar { Property1 = "abc", Property2 = "def" }); XmlSerializer ser = new XmlSerializer(typeof(Foo)); using (FileStream fs = new FileStream(@"c:\sertest.xml", FileMode.Create)) { ser.Serialize(fs, f); }

if we have XML file like this : <picturecollection> <photo> <name>One</name> <path>somepath1</path> </photo> <photo> <name>Two</name> <path>somepath2</path> </photo> </picturecollection> we can use This Code to return List of Class XDocument xdoc = XDocument.Load(Server.MapPath(@"\Photo.xml")); List pics = (from xml in xdoc.Elements("PictureCollection").Elements("Photo") select new Pic { PicName = xml.Element("name").Value, TbPath = xml.Element("path").Value }).ToList(); public class Pic { public string PicName {get; set;} public string TbPath { get; set; } }

First you must create account on  Here  to get API_Key you can read document from Here once you get API_Key you can use Code to get data : private String GetCityName(string IP) { string _City = ""; try { string _URL = null; string _ApiKey = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"; _URL = "http://api.ipinfodb.com/v3/ip-country/?key=" + _ApiKey + "&format=xml&ip=" + IP; //Get google response as XML doc dynamic xmlDoc = new System.Xml.XmlDocument(); xmlDoc.Load(_URL); System.Xml.XmlNode _root = xmlDoc.DocumentElement; System.Xml.XmlNodeList _CityName = xmlDoc.GetElementsByTagName("cityName"); System.Xml.XmlElement _CityNameElement = (System.Xml.XmlElement)_CityName.Item(0); _City = _CityNameElement.FirstChil...

String Format for Double [C#] The following examples show how to format float numbers to string in C#. You can use static method String.Format or instance methods double.ToString and float.ToString . Digits after decimal point This example formats double to string with fixed number of decimal places . For two decimal places use pattern „ 0.00 “. If a float number has less decimal places, the rest digits on the right will be zeroes. If it has more decimal places, the number will be rounded. [C#] // just two decimal places String .Format( "{0:0.00}" , 123.4567); // "123.46" String .Format( "{0:0.00}" , 123.4); // "123.40" String .Format( "{0:0.00}" , 123.0); // "123.00" Next example formats double to string with floating number of decimal places . E.g. for maximal two decimal places use pattern „ 0.## “. [C#] // max. two decimal places String .Format( "{0:0.##}" , 123.4567); ...
