C# Multidimensional Arrays As discussed in the previous chapter, Arrays in C# will support multi-dimensional arrays. In c#, a multidimensional array is an array that contains more than one dimension to represent the elements in a tabular format like rows and columns.In c#, multidimensional arrays can support either two or three-dimensional series. To create multi-dimensional arrays, we need to use a comma (,) separator inside the square brackets. C# Multi-Dimensional Array Declaration In c#, Multidimensional Arrays can be declared by specifying the data type of elements followed by the square brackets [] with comma (,) separator. The following are examples of creating two or three-dimensional arrays in the c# programming language. Question: Create a complete C# program that will compute the average of all elements in array x int [,] x = new int[4, 5] { { 4, 5, 6, 2, 12 }, { 10, 25, 33, 22, 11 },{ 211, 32, 43, 54, 65 }, { 3, 2, 1, 5, 6 } }; Average Solution Use for loop get array x elements values Add values Divide results by no. of values Code using System; namespace Module7 { public class Module7 { public static void Main(string[] args) { //initilizing array int[,] x = new int[4, 5] { { 4, 5, 6, 2, 12 }, { 10, 25, 33, 22, 11 }, { 211, 32, 43, 54, 65 }, { 3, 2, 1, 5, 6 } }; Console.WriteLine("---Two dimensional array elements---"); // use for loop get array x elements for(int y=0; y<4; y++) { int sum = 0; double avg =…

Question: Create a complete C# program that will simulate a log-in process. If the username and password are both correct the program will display “Log-in Successful”, otherwise it will display “Invalid Log-in details” FlowChart: C# Logical Operators: Code Answer: using System; namespace Module6 { class module6 { static void Main(string[] args) { string emailid, password; //use readline get user input Console.WriteLine("Plz enter u Emaill address :"); emailid = Console.ReadLine(); Console.WriteLine("Plz enter u Password"); password = Console.ReadLine(); //use if else to decision input data contains value if (emailid.Contains("[email protected]") && (password.Contains("d123456"))) { Console.WriteLine("Your Log-in Was Successful!"); } else { Console.WriteLine("Invalid Log-in details"); } Console.ReadLine(); } } } Reference C# Logical Operators with Exampleshttps://www.tutlane.com/tutorial/csharp/csharp-logical-operators-with-examples C# String Contains()https://www.javatpoint.com/csharp-string-contains

Example explainedLine 1: using System means that we can use classes from the System namespace. Line 2: A blank line. C# ignores white space. However, multiple lines makes the code more readable. Line 3: namespace is used to organize your code, and it is a container for classes and other namespaces. Line 4: The curly braces {} marks the beginning and the end of a block of code. Line 5: class is a container for data and methods, which brings functionality to your program. Every line of code that runs in C# must be inside a class. In our example, we named the class Program. Don't worry if you don't understand how using System, namespace and class works. Just think of it as something that (almost) always appears in your program, and that you will learn more about them in a later chapter. Line 7: Another thing that always appear in a C# program, is the Main method. Any code inside its curly brackets {} will be executed. You don't have to understand the keywords before and after Main. You will get to know them bit by bit while reading this tutorial. Line 9: Console is a class of the System namespace, which has a WriteLine() method that is used to output/print text. In our example it will output "Hello World!". If you omit the using System line, you would have to write System.Console.WriteLine() to print/output text. Note: Every C# statement ends with a semicolon ;. Note: C# is case-sensitive: "MyClass" and "myclass" has different meaning. Note: Unlike Java, the…

【Steam不再提供中国内地的CM服务器】CM（Connection Manager）服务器，用于 Steam 帐户登录认证、好友在线状态、聊天和游戏邀请等等方面。目前 Steam 获取的服务器列表已不存在中国内地服务器。 由于steam不再提供中国内地的CM服务器，导致每周末晚高峰的时期，steam登录及其困难。写这篇文章是为了记录处理这个问题的过程和解决办法，希望能帮到大家； 解决方案如下 方法一 指定客户端连接协议启动客户端 直接给steam.exe的快捷方式加参数-tcp或-websocket来指定连接协议启动客户端 -tcp模式 -websocket模式 为改善使用体验，我添加了一个启动目录，使得在启动时候可以选择启动模式如果此方法无法连接登录，请选择方法二 方法二 添加hosts,在默认情况下指定CM服务器 / 强制指定使用WS连接启动客户端 使用Dogfight360的工具添加host 指定MC服务器 ，然后通过WS连接模式启动客户端即可 点击检测延迟选择延迟较低的服务（晚高峰建议避开新加坡，日本，香港 我这里选择卢森堡，具体根据您的互联网运营商选择） 选择指定的MC服务器 点击应用选中 通过-websocket连接模式启动即可 此文章并不能保证百分之百可以解决。通过希望通过此文章能够让您尝试多一个方法去解决此问题。 参考阅读：Dogfight 360的博客 https://www.dogfight360.com/blog/knowledge-base/fix_steamlogin/ Steam status https://steamstat.us/ 其乐 https://keylol.com/
