26.1 Extension methods擴充函數Extension methods are static methods that can be invoked using instance method syntax. In effect, extension methods make it possible to extend existing types and constructed types with additional
26.1 Lambda expressions Lambda 運算式C# 2.0 introduces anonymous methods, which allow code blocks to be written “in-line” where delegate values are expected. While anonymous methods provide much of the expressive power of functional programming
26.1.1 Type inference 類型推斷When a generic method is called without specifying type arguments, a type inference process attempts to infer type arguments for the call. Lambda expressions passed as arguments to the generic method participate in this
A. 1000! 有幾位,為什麼?先上代碼,一看就明白 int n = 1000; double sum = 0; for (int i = 1; i <= n; i++) { sum = sum + Math.Log10(i); } Console.WriteLine("The '1000! has %{
26.1 Implicitly typed local variables隱式類型化的本地變數In an implicitly typed local variable declaration, the type of the local variable being declared is inferred from the expression used to initialize the variable. When a local variable declaration
