C # type conversion
Type conversion from type casting is fundamentally, or that convert data from one type to another type. In C #, type casting in two forms:
- Implicit type conversion - these conversions are C # default conversion carried out in a safe manner.For example, small integer type to a larger integer type, conversion from a derived class to the base class.
- Explicit type conversion - these conversions are using predefined functions through the user explicitly done.Explicit conversions require a cast operator.
The following example shows an explicit type conversion:
namespace TypeConversionApplication { class ExplicitConversion { static void Main (string [] args) { double d = 5673.74; int i; // Cast double to int i = (int) d; Console.WriteLine (i); Console.ReadKey (); } } }
When the above code is compiled and executed, it produces the following results:
5673
C # type conversion
C # provides the following built-in type conversion methods:
序号 | 方法 & 描述 |
---|---|
1 | ToBoolean 如果可能的话,把类型转换为布尔型。 |
2 | ToByte 把类型转换为字节类型。 |
3 | ToChar 如果可能的话,把类型转换为单个 Unicode 字符类型。 |
4 | ToDateTime 把类型(整数或字符串类型)转换为 日期-时间 结构。 |
5 | ToDecimal 把浮点型或整数类型转换为十进制类型。 |
6 | ToDouble 把类型转换为双精度浮点型。 |
7 | ToInt16 把类型转换为 16 位整数类型。 |
8 | ToInt32 把类型转换为 32 位整数类型。 |
9 | ToInt64 把类型转换为 64 位整数类型。 |
10 | ToSbyte 把类型转换为有符号字节类型。 |
11 | ToSingle 把类型转换为小浮点数类型。 |
12 | ToString 把类型转换为字符串类型。 |
13 | ToType 把类型转换为指定类型。 |
14 | ToUInt16 把类型转换为 16 位无符号整数类型。 |
15 | ToUInt32 把类型转换为 32 位无符号整数类型。 |
16 | ToUInt64 把类型转换为 64 位无符号整数类型。 |
The following examples of the different types of value are converted to string type:
namespace TypeConversionApplication { class StringConversion { static void Main (string [] args) { int i = 75; float f = 53.005f; double d = 2345.7652; bool b = true; Console.WriteLine (i.ToString ()); Console.WriteLine (f.ToString ()); Console.WriteLine (d.ToString ()); Console.WriteLine (b.ToString ()); Console.ReadKey (); } } }
When the above code is compiled and executed, it produces the following results:
75 53.005 2345.7652 True
