bool类型是比较和相等运算符的结果类型。bool表达式可以是if、do、while和for语句中以及条件运算符?:中的控制条件表达式。 bool类型的默认值为false。 字符类型(char) char类型关键字是.NET System.Char结构类型的别名,它表示Unicode UTF-16字符。 char类型的默认值为\0,即U+0000。 char类型支持比较、相等、增量和...
C# 也支持 foreach 循环,使用 foreach 可以迭代数组或者一个集合对象。 C# 的 foreach 循环可以用来遍历集合类型,例如数组、列表、字典等。它是一个简化版的 for 循环,使得代码更加简洁易读。 以下是 foreach 循环的语法: foreach(varitemincollection){// 循环} collection 是要遍历的集合,item 是当前遍历到的...

C# iteration statements (for, foreach, do, and while) repeatedly execute a block of code. You use those statements to create loops or iterate through a collection.
Code that changesforeachloop variable (which is not allowed in C#) are convertedas-is, which means the resulting code will not compile cleanly. Not supported features Property / Event definition Macros Literals Regular expressions Note that any unsupported language construct (a.k.a, AST node type...
嵌套循环 您可以在 while、for 或 do..while 循环内使用一个或多个循环。 循环控制语句 循环控制语句更改执行的正常序列。当执行离开一个范围时,所有在该范围中创建的自动对象都会被销毁。 C# 提供了下列的控制语句。点击链接查看每个语句的细节。 控制语句描述 break 语句 终止loop 或switch 语句,程序流将继续执...
Thecontinuestatement starts a new iteration of the closest enclosingiteration statement(that is,for,foreach,while, ordoloop), as the following example shows: C# for(inti =0; i <5; i++) { Console.Write($"Iteration{i}: ");if(i <3) { Console.WriteLine("skip");continue; } Console.Wr...
