在c＃中循环数组 [英] Looping in array in c#

问题描述

我是asp.net和c＃的新手。现在我想在c＃中循环遍历数组。你能举个例子吗？在此先感谢

Hi, i am very new to asp.net and c#. Now i want to loop through the array in c#. can you give me a example. Thanks in advance

如果您不知道如何编写一个访问数组中每个值的简单循环，我相信您在C＃编程方面处于基础零点，更不用说使用ASP了.NET。



没有错误处于地面零点;我们都从那里开始了:)而且，好消息是：如果你现在就开始，在一两个星期内你再也不会认为你对C＃是新的了。



我已经多次在这里发布了我认为在C＃.NET中开发基本能力的好资源（一些免费）：[ ^ ]。



我鼓励您首先专注于掌握C＃ .NET编程的基本要素;有一些你需要学习的东西，几乎所有的编程语言都是常见的。



我会担心如果你不是从C＃的基础开始然后继续前进到复杂的ASP.NET世界将是非常困难的。



要点（imho）：



在.NET C＃中创建更高级别的对象：这些将是NameSpace，Class（静态和非静态），Struct，Enum



范围，表示如何管理您创建的不同对象的名称在编译/执行代码的任何给定时刻进行评估



Flow-Of -Control：循环：for，foreach，while，do。如果/ Else和Switch / Case结构。



了解.NET类型：值类型，引用类型;理解类型转换。



变量（在.NET'字段中）如何声明它们，控制它们的可访问性（范围）。



属性



方法（静态和非静态）：传递参数，返回结果。通过值传递，使用'out和'ref传递。



简单数学运算符。运算符优先级。



布尔比较。理解'null，string.IsEmpty等的使用



基本数据结构：数组，通用列表。

If you do not know how to write a simple loop that accesses each value in an Array, I believe you are at ground-zero in terms of programming in C#, let alone using ASP.NET.

There's nothing wrong with being at "ground-zero;" we all start there :) And, the good thing is: if you start now, within a week or two you will never think you are "new" to C# again.

I've posted several times here on what I think are good resources (some free) for developing a basic competency in C# .NET: [^].

I encourage you to focus your study on first mastering the essential elements of C# .NET programming; there are certain things you need to learn which are common to almost all programming languages.

I would be concerned that if you do not start with a "foundation" in C# then moving on to the complex world of ASP.NET is going to be very difficult.

Essentials (imho):

Creating "Higher-Level Objects:" in .NET C# those would be NameSpace, Class (static and non-static), Struct, Enum

"Scope" which means how to manage how the names of different objects you have created are evaluated at any given moment in the compilation/execution of your code

Flow-Of-Control: Loops: for, foreach, while, do. If/Else and Switch/Case structures.

Understanding .NET Types: Value Types, Reference Types; understanding Type conversion.

Variables (in .NET 'Fields) how to declare them, control their accessibility (scope).

Properties

Methods (static and non-static): passing parameters, returning results. passing by value, passing using 'out and 'ref.

Simple Math operators. operator precedence.

Boolean comparison. understanding use of 'null, string.IsEmpty, etc.

Basic Data Structures: Arrays, Generic Lists.

你好neethu ..你问题的答案是......



参考循环数组

Hi neethu..here is the answer for your question..

ReferLoop through array

int[] nums = {
                         72,
                         52,
                         63,
                         852,
                         421,
                         86
                     };
 
        lbl_dispaly.Text = "Numbers <br />";
        foreach (int num in nums)
        {
            lbl_dispaly.Text += num.ToString() + "<br />";
        }
