Built-in types in C#

Built-in types in C#

1. Boolean type: only true or false
2. Integral types: sbyte, byte, short, ushort, int, uint, long, ulong, char
3. Floating types: float and double
4. Decimal types
5. String type

using System;
class Program
{
    static void Main()
    {
        //boolean data type declaration
        bool b = true;
        Console.WriteLine(b);

        //Integral types
        Console.WriteLine("sbyte: min value: {0} , max value: {1}", sbyte.MinValue, sbyte.MaxValue);
        Console.WriteLine("byte: min value: {0} , max value: {1}", byte.MinValue, byte.MaxValue);
        Console.WriteLine("short: min value: {0} , max value: {1}", short.MinValue, short.MaxValue);
        Console.WriteLine("ushort: min value: {0} , max value: {1}", ushort.MinValue, ushort.MaxValue);
        Console.WriteLine("int: min value: {0} , max value: {1}", int.MinValue, int.MaxValue);
        Console.WriteLine("uint: min value: {0} , max value: {1}", uint.MinValue, uint.MaxValue);
        Console.WriteLine("long: min value: {0} , max value: {1}", long.MinValue, long.MaxValue);
        char ch = '%';
        Console.WriteLine("char: {0}", ch);

        //Floating types        
        Console.WriteLine("float: min value: {0} , max value: {1}", float.MinValue, float.MaxValue);
        Console.WriteLine("double: min value: {0} , max value: {1}", double.MinValue, double.MaxValue);

        //Decimal type
        decimal myMoney = 300.5m;
        Console.WriteLine(myMoney);
    }
}

Escape sequence in C#

When we need to print special characters like double quotes, backslash, etc. We can make use of the escape sequence as below:

using System;
class Program
{
    static void Main()
    {        
        Console.WriteLine("\"Mayuresh Joshi\"");
    }
}

Output

Verbatim Literal in C#

Strings starts with @ symbol are called as verbatim strings. Basically the @ symbol tells the string constructor to ignore escape characters and line breaks.

using System;
class Program
{
    static void Main()
    {
        string str = "\\Mayuresh\\TestFolder\\NewFolder";
        Console.WriteLine(str);

        //using Verbatim Literal
        string str1 = @"\Mayuresh\TestFolder\NewFolder";
        Console.WriteLine(str1);
    }
}

Output:
