C# Types of Assemblies

In C#, an assembly is a collection of code, resources, and metadata that is used to deploy and run an application. There are two types of assemblies in C#: private and shared.

Private Assemblies

A private assembly is an assembly that is used by a single application. It is stored in the application's directory or a subdirectory and is not designed to be shared among multiple applications. Private assemblies are typically used for small applications or utilities.

Syntax

To create a private assembly in C#, follow these steps:

1. Create a new project in Visual Studio.
2. Write the code for the assembly.
3. Build the project.
4. The resulting DLL file is the private assembly and can be used by the application.

Example

Let's say we have a C# console application that needs to use a set of utility functions. We can create a private assembly to encapsulate these functions and make them available to the console application.

Here's how we can create the utility functions in a new C# class library project:

public static class Utilities {
    public static int Multiply(int a, int b) {
        return a * b;
    }
}

We then build the project, which will create the DLL file that contains the utility functions. To use the private assembly in our console application, we add a reference to the DLL file and call the utility functions:

using System;
using MyUtilities;

static void Main(string[] args) {
    int result = Utilities.Multiply(5, 10);
    Console.WriteLine(result); // Output: 50
}

Output

When we run the example code above, the output will be:

50

This is because we called the Multiply function from the Utilities class and passed in the arguments 5 and 10, which returned the value 50.

Explanation

In the example above, we created a private assembly by writing a set of utility functions in a new C# class library project. We then built the project, which generated the DLL file containing the utility functions.

In our console application, we added a reference to the DLL file and called the utility functions to multiply two integers. The Multiply function returned the product of the two integers, which we then printed to the console.

Use

Private assemblies are useful for small applications or utilities that do not need to be shared among multiple applications. They allow you to encapsulate code and resources in an assembly that can be easily reused within a single application.

Important Points

• Private assemblies are stored in the application's directory or a subdirectory.
• Private assemblies are not designed to be shared among multiple applications.
• Private assemblies are useful for encapsulating code and resources in an assembly that can be easily reused within a single application.

Summary

In this tutorial, we discussed private assemblies in C# and provided an example. We covered the syntax, example, output, explanation, use, and important points of private assemblies in C#. With this knowledge, you can now create private assemblies in your C# code to encapsulate code and resources that can be easily reused within a single application.
