The ?? operator is called the null-coalescing operator and is used to define a default value for a nullable value types as well as reference types. It returns the left-hand operand if it is not null; otherwise it returns the right operand.
Syntax: if(condition) { // code block to be executed when if condition evaluates to true. } Example: if Statement. int i = 10, j = 20; if (i < j) { Console.WriteLine("i is less than j"); } . if (i > j) { Console.WriteLine("i is greater than j"); } Try it. Output: i is less than j.
14 Σεπ 2021 · If condition is True, the statements following Then are executed. If condition is False, each ElseIf statement (if there are any) is evaluated in order. When a True elseifcondition is found, the statements immediately following the associated ElseIf are executed.
13 Ιουλ 2009 · Use the C# coalesce operator: ?? // if Value is not null, newValue = Value else if Value is null newValue is YournullValue var newValue = Value ?? YourNullReplacement;
When an if statement's condition evaluates to true, C# executes all code between its braces ({ and }). This way we code decisions in our C# program.
5 Φεβ 2023 · If Range("a2").Value > 0 Then Range("b2").Value = "Positive" ElseIf Range("a2").Value < 0 Then Range("b2").Value = "Negative" Else Range("b2").Value = "Zero" End If. If-Else. The most common type of If statement is a simple If-Else: Sub If_Else() If Range("a2").Value > 0 Then Range("b2").Value = "Positive" Else Range("b2").Value = "Not Positive ...
if (value), if (!value), if (flag == value), if (value == true), if (value == false), depending on what's to be achieved, are valid code. E.g. if (value == true) is very useful when value is a nullable boolean, because if (value) will give a syntax error, and if (value.Value == true) will throw exception if you didn't ensure that value is not ...
