C# type conversion

C# is a modern, general-purpose, object-oriented programming language developed by Microsoft and approved by Ecma and ISO.

C# was developed by Anders Hejlsberg and his team during the development of the .Net framework.

C# is designed for the Common Language Infrastructure (CLI). The CLI consists of executable code and a runtime environment that allows the use of a variety of high-level languages ​​on different computer platforms and architectures.

C# type conversion syntax

Type conversion is fundamentally type casting, or converting data from one type to another. In C#, type casting comes in two forms:

Implicit type conversions - These conversions are C#'s default conversions that are performed in a safe manner without causing data loss. For example, converting from a small integer type to a large integer type, and from a derived class to a base class.

Explicit type conversion - explicit type conversion, that is, forced type conversion. Explicit conversion requires a cast operator and causes data loss.

C# type conversion example

namespace TypeConversionApplication{
    class ExplicitConversion
    {
        static void Main(string[] args)
        {
            double d = 5673.74;
            int i;
            // 强制转换 double 为 int
            i = (int)d;
            Console.WriteLine(i);
            Console.ReadKey();
            
        }
    }}
