Implicit casting as in Case 1, gives compilation error as there is a possible loss of imformation. char is 'unsigned' while byte is 'signed' and therefore am implicit conversion there might result in loss of information and hence discouraged. [ August 22, 2006: Message edited by: Mannu ...
Data Type Casting in C# with Examples. This Tutorial Explains Explicit & Implicit Conversion, Convert To String & Data Type Conversion Using Helper Classes.
Consider casting one of the operands instead. V3201. Return value is not always used. Consider inspecting the 'foo' method. V3202. Unreachable code detected. The 'case' value is out of the range of the match expression. V3203. Method parameter is not used. V3204. The expression is ...
使用Casting null并不能作为灵感编译,并且来自Eric Lippert的评论: 这表明了一个有趣的案例."uint x =(int)0;" 即使int不能隐式转换为uint也会成功. 我们知道这不起作用,因为object无法分配到string: stringx = (object)null; Run Code Online (Sandbox Code Playgroud) ...
Our discussion of type compatibility will touch on the subjects of type conversion (also called casting), which changes a value of one type into a value of another; type coercion, which performs a conversion automatically in certain contexts; and nonconverting type casts, which are sometimes ...

This section describes type casting supported in Java: up casting (widening reference conversion) and down casting (narrowing reference conversion). Cast operation can be written explicitly with the cast operator (T), or implicitly with no operator.©...
