To make HTTP requests using the HttpClient class in .NET, it’s crucial to follow best practices for efficient resource management and to ensure high performance in your applications. This guide elaborates on creating an HttpClient, making various types of HTTP requests, handling responses, and properly managing potential HTTP errors, with enhanced explanations and examples. Best…
To send an HTTP POST request in .NET, particularly using the HttpClient class, involves several key steps including creating an instance of HttpClient, constructing the request, sending it, and handling the response. The HttpClient class is part of the System.Net.Http namespace and is the recommended approach due to its asynchronous and high-performance nature. Below, I’ll…
The [Flags] attribute in C# is used to declare an enumeration type that can be treated as a bit field; that is, a set of flags. It allows an instance of the enumeration to store a combination of values. Typically, each value in such an enumeration is a power of two, meaning each one represents…
Creating a deep copy of an object in C# can be achieved through various methods, including the use of the ICloneable interface, which is one of the simplest approaches. However, it’s crucial to understand the nuances and potential pitfalls of each approach to ensure it meets your specific requirements. Let’s delve into the details of…
Let’s create 5 examples to demonstrate how to perform a left outer join using LINQ in C#. We’ll start with simpler examples and gradually introduce more complexity. Example 1: Basic Left Outer Join Suppose we have two collections: Employees and Departments. Each Employee is associated with a Department by DepartmentId. We want to list all…
Calling an asynchronous method from a synchronous method in C# can be tricky, especially if you need to maintain the context for UI updates or other context-specific operations. However, it’s possible under certain circumstances, but you need to be cautious of potential pitfalls like deadlocks. Here’s how you can approach it: Solution A: Using Task.WaitAndUnwrapException…
Deserializing an XML document into a C# object is a common task when working with XML data. One efficient way to accomplish this is by first generating C# classes that correspond to the structure of the XML document and then using the XmlSerializer class to deserialize the XML into instances of these classes. Here’s a…
To address case sensitivity issues when checking if a string contains another substring in C#, the .Contains method itself doesn’t provide an overload to specify case-insensitivity directly. However, you can achieve this functionality by using the .IndexOf method which does allow you to specify StringComparison criteria, including case-insensitive comparisons. Here’s a practical way to extend…
Yes, it’s possible to get the value of a property using reflection by passing the object and a string that represents the name of the property. The method you’ve outlined is a basic but effective way to achieve this. Here’s a more detailed explanation and an expanded example that includes basic validation to handle potential…
To determine if a file is in use in C#, particularly for scenarios where you wish to modify a file but want to avoid the exception that occurs if the file is currently being accessed by another process, employing a try-catch block to handle IOException is a practical approach. Here’s a closer look at how…
