Foreach loop in C# runs upon a single thread and processing takes place sequentially one by one. Foreach loop is a basic feature of C# and it is available from C# 1.0. Its execution is slower than the Parallel.Foreach in most of the cases. C# Parallel.ForEach loop Parallel.ForEach loo...
foreach 循环设置数组元素的计算器。 classForEachTest{staticvoidMain(string[]args){int[]fibarray=newint[]{0,1,1,2,3,5,8,13};foreach(intelementinfibarray){System.Console.WriteLine(element);}System.Console.WriteLine();// 类似 foreach 循环for(inti=0;i<fibarray.Length;i++){System.Console...
Let's start with C# for loop. for loop in C# The for loop iterates through items until a certain condition is true. You give an initial statement, a condition for which the loop is to be iterated until it gets false, and a statement that will be executed after every successful block ...
csharp List<int> numbers = new List<int> { 1, 2, 3, 4, 5 }; foreach (int number in numbers) { if (number == 3) { Console.WriteLine("Found 3, breaking out."); break; // 跳出循环 } Console.WriteLine(number); } Console.WriteLine("Exited the foreach loop.")...
摘自:Effective_CSharp 改善C#程序的50种方法 使用foreach来取代其它的循环结构。检查下面的三个循环: int [] foo = new int[100]; //Loop1: foreach (int i in foo) Console.WriteLine(i.ToString()); //Loop2: for (int index = 0; index < foo.Length; index++) ...
Console.WriteLine();//Use "foreach" to loop two-dimension array(使用foreach循环二维数组)Console.WriteLine("User 'foreach' to loop two-dimension array"); foreach (var item in nVisited) Console.Write(item.ToString()); foreach只用一行代码就将所有元素循环了出来,而for循环则就需要很多行代码才可...
Here, we loop over the elements one by one. foreach (int i in Enumerable.Range(0, vals.GetLength(0))) { foreach (int j in Enumerable.Range(0, vals.GetLength(1))) { Console.Write($"{vals[i, j]}"); } Console.WriteLine(); ...
foreach(varitemincollection){// 循环} collection 是要遍历的集合,item 是当前遍历到的元素。 以下实例有三个部分: 通过foreach 循环输出整型数组中的元素。 通过for 循环输出整型数组中的元素。 foreach 循环设置数组元素的计算器。 实例 classForEachTest ...
