Let’s say you have a List of T. And there are Property1, Property2, Property3 in T. If you want to change the value of Property2 in T then you can use: var myList = List<T>; foreach (var item in myList) { item.Property2 = newValue; } or var myList = List<T>; myList.ForEach(x => x.Proprty2 = newValue); […]
DECLARE @MyValue int SELECT @MyValue = Column1 WHERE Column2 > 50 IF @MyValue IS NULL BEGIN RAISEERROR(‘This is my custom message from SQL.’, 16, 1) END ELSE SELECT MyValue END Use an error code within 11-16, or just use 16 for a “general” case. RAISERROR(‘This is my custom message from SQL.’,16,1) Why? Here’s summary of […]
The IndexOf() method returns the index number of the first matched character whereas the LastIndexOf() method returns the index number of the last matched character. using System; public class StringExample { public static void Main(string[] args) { string s1 = “Hello C#”; int first = s1.IndexOf(‘l’); int last = s1.LastIndexOf(‘l’); Console.WriteLine(first); Console.WriteLine(last); } } Output: […]
DateTime myDate; if(DateTime.TryParse(txtBirthDate.Text, out myDate)) { //Valid Date } else { //Invalid Date }
string myList = “9,3,12,43,2”; List<int> intList = myList.Split(‘,’).Select(int.Parse).ToList();
List<int> list = new List<int>() {1,2,3}; string.Join<int>(“,”, list) Join has generic overloads. It is so much easier to use it in that way to convert your list to the different types.
@Html.ListBox( “Countries”, ViewBag.AllCountries as MultiSelectList, new { @class = “form-control”, data_placeholder = “Choose a Country…” } )
string sNumbers = “1,2,3,4,5”; var numbers = sNumbers.Split(‘,’).Select(Int32.Parse).ToList();
new[] {“,”, “/”}.Any(input.Contains) or you can use Regex Regex.IsMatch(input, @”[,/]”);
Table below shows the default value for the different predefined data types. Type Default sbyte, byte, short, ushort, int, uint, long, ulong 0 char ‘\x0000’ float 0.0f double 0.0d decimal 0.0m bool false object null string null As you can see, for the integral value types, the default value is zero. The default value for […]
string myValueToSplit = “Istanbul, Tokyo, Seoul, Bangkok, Bali, Minsk, Belgrade, Kiev”; var theFirstValue = myValueToSplit.Split(‘,’)[0]; //OUTPUT: theFirstValue = “Istanbul” //You can change [0] as you wish. //For example, if you want to get Kiev, make it [7]
You can assign an id to the <script> element and passing the arguments as data-* attributes. The resulting <script> tag would look something like this:
You need to define a length when specifying the varchar parameter: SqlParameter TheFirstJob = cmd.Parameters.Add(“@spParam”, SqlDbType.VarChar, 50); Note: You should use the same length as defined in your SQL Server stored procedure.
