Introduction: This article records the use of IniParse to read and write ini configuration files in C sharp programming. Read the Mysql database configuration file in the ini file for database connection: If you want to read configuration information from an .ini file, you can use a third-party library such as IniParser. Here’s how to do it using the IniParser library: First, you need to install IniParser using the NuGet package manager. In Visual Studio, you can execute the following command through the NuGet package manager console: Install-Package IniParser Then, create a config.ini file and add the following content: ...

Reason I haven’t done maintenance for an Internet cafe for a long time. When I did some maintenance for a Japanese Internet cafe recently, I had to use a delayed startup program because I had to perform some initialization procedures after the workstation was powered on. (The program was written by a senior and helped a lot. Bow) But it cannot run normally under Japanese system ** error is as follows: ** If you want to solve this error, you need to change the program region to China in the regional options. This will create a new problem. Some programs will use the region to determine the user’s location, which will cause some software to not run properly. ...

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 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("ydsgsdg@dsadas.edu.ph") && (password.Contains("d123456"))) { Console.WriteLine("Your Log-in Was Successful!"); } else { Console.WriteLine("Invalid Log-in details"); } Console.ReadLine(); } } } Reference C# Logical Operators with Examples https://www.tutlane.com/tutorial/csharp/csharp-logical-operators-with-examples ...
