Difference between WriteLine and Write method in C#?
- To print the data on the console output screen Console.Write() and Console.WriteLine() method can be used in C#. Console is a predefined class of System namespace. While Write() and WriteLine() both are the Console Class methods.
- The WriteLine method prints one or more object in a single line with a new line character inserted at the end. This means any subsequent output will be printed in a new line.
- The Write method is used to print one or more objects in a single line without inserting a new line character at the end.
- In the Write method, the cursor remains at the same line, while in WriteLine it moves to the next.
C# Naming Standards
There are following three terminologies being used to declare C# and .NET naming standards:
- Camel Case (camelCase): In this standard, the first letter of the word always in small letter and after that each word starts with a capital letter.
- Pascal Case (PascalCase and also called UpperCamelCase): In this the first letter of every word is in capital letter.
- Underscore Prefix (_underScore): For underscore ( _ ), the word after _ use camelCase terminology.
- Use PascalCase for class names. Try to use noun or noun phrase for class name. Do not give prefixes. Do not use underscores.
- Use PascalCase for method names. Use maximum 7 parameters in a method.
- Use camelCase with method arguments and local variables.
- Use letter "I" as prefix with name of interface. After letter I, use PascalCase.
- Always try to use camelCase terminology prefix with underscore ( _ ) for Private Member Variable.
- Use PascalCase for public member variable.
- Use PascalCase for namespace.
- Use PascalCasing in field names. Do not use a prefix and underscores for field names.
C# Comments
- Comments can be used to explain C# code, and to make it more readable.
- Comments are English words used for Code documentation.
- C# supports Single line comment and multiple lines comment.
- Comments in C# make the code Readable. It also make the code disable from execution
- Single-line comments start with two forward slashes ( // ). Any text between // and the end of the line is ignored by C# (will not be executed). Multi-line comments start with /* and ends with */.
Comments Syntax in C#:
Use // for Single line comments
Use /* ……
………..
…………..
*/ for Multiple lines comments
