Use the convert command for explicit conversion

UseConvertCommand to convert the display:

Command	Result
convert. toboolean ( Val )	Val convert to bool
convert. tobyte ( Val )	Val convert to byte
convert. tochar ( Val )	Val convert to char
convert. todecimal ( Val )	Val convert to decimal
convert. todouble ( Val )	Val convert to double
convert. toint16 ( Val )	Val convert to short
convert. toint32 ( Val )	Val convert to int
convert. toint64 ( Val )	Val convert to long
convert. tosbyte ( Val )	Val convert to sbyte
convert. tosingle ( Val )	Val convert to float
convert. tostring ( Val )	Val convert to string
convert. touint16 ( Val )	Val convert to ushort
convert. touint32 ( Val )	Val convert to uint
convert. toyint64 ( Val )	Val convert to ulong

The convert command must be used to display the strings provided by the conversion, which must be a valid expression of values and not overflow. The valid expression of a value is: an optional Symbol (+ or-), followed by a 0-or multi-digit word, followed by a single or multiple-digit word, next is an optional E or E, followed by an optional rich and one-or multiple-digit word (before or after this sequence) and space. With this optional additional data, we can see that a complex string such as-1.2564e-24 is a numerical value.

 

Note:ValIt can be various types of variables. If these commands cannot process these types of variables, the compiler will tell you

Table conversion names are slightly different fromC #Type name, because these commands come from. NET FrameworkOfSystemNamespace insteadC #Itself. In this wayC #Other. NetUse in compatible languages

One of the notes for these conversions is that they always need to perform overflow checks. The cheched and unchecked keywords and project property settings do not have any effect.
