- How to use exception filters and exception handling in C#
- How to use exception filters and exception handling in C# requires specific code examples. Exceptions are errors or unexpected situations that occur during program running. In C#, exceptions are handled by throwing and catching. Exception handling is a key part of ensuring the normal operation of the program. In C#, exception filters and exception handling are two common ways of handling exceptions. Exception filters allow us to filter and handle exceptions before catching them. It uses the when keyword to specify the conditions for the exception filter. Here is an example: try{

- How to use properties and automatically implemented properties to simplify code in C#
- How to use properties and automatically implemented properties in C# to simplify code requires specific code examples. In C# programming, using properties and automatically implemented properties can help us simplify the code and improve the readability and maintainability of the code. Properties allow us to access and change the state of an object by encapsulating fields, and automatically implementing properties further simplifies the property creation process. Properties are a special method used to get and set object data. In C#, properties allow us to access and change fields while performing other

- Common data type conversion problems and solutions in C#
- Common data type conversion problems and solutions in C# In C#, data type conversion is a common problem. Since C# is a strongly typed language, the types of variables must match when calculating or assigning values. Therefore, when we need to convert one data type to another data type, we may encounter various problems. This article will introduce common data type conversion problems and provide corresponding solutions and specific code examples. String to integer type problem: When we need to convert a string to an integer type (int

- How to use delegates and event handlers in C#
- How to use delegates and event handlers in C# requires specific code examples. In C#, delegates and event handlers are two very important concepts that can be used to implement event-driven programming models. Delegates provide a mechanism for passing methods as parameters, while event handlers are used to handle methods for specific events. This article will introduce in detail how to use delegates and event handlers in C#, and give specific code examples. First, we need to understand what delegation is. A delegate can be viewed as a reference to a method, which can be used to store specific

- C# program for searching directories and listing files
- Searching directories and listing files are common tasks in many applications. In C#, we can use the Directory and File classes provided by the System.IO namespace to perform these tasks. In this article, we will explore how to write a C# program to search directories and list files. Method: Using Directory.GetFiles() The easiest way to search a directory and list files in C# is to use the Directory.GetFiles() method. This method returns an array of strings representing the paths to all files in the specified directory that match the specified search pattern. This is how we can list all files in a directory using Directory.GetFiles() method
