C# Output

In C#, output refers to the information that is displayed to the user or saved to a file. The most common way to output information in C# is to use the Console class. The Console class provides methods for printing text, numbers, and other types of data to the console window.

Here are some examples of how to output information to the console using the Console class:

Printing text to the console:

Console.WriteLine("Hello, World!");

Printing a number to the console:

int number = 10;

Console.WriteLine(number);

Printing multiple values to the console:

string name = "John Doe";

int age = 30;

Console.WriteLine("Name: {0}, Age: {1}", name, age);

Formatting output:

double pi = 3.14159;

Console.WriteLine("Pi: {0:0.0000}", pi);

In addition to printing to the console, C# can also output information to files. To do this, you can use the StreamWriter class. The StreamWriter class provides methods for writing text, numbers, and other types of data to a file.

Here is an example of how to write text to a file using the StreamWriter class:

string text = "This is some text.";

StreamWriter writer = new StreamWriter("output.txt");

writer.WriteLine(text);

writer.Close();

This code creates a new StreamWriter object for the file "output.txt" and writes the text "This is some text." to the file. The Close() method is called to close the file and flush any remaining data to disk.
