Convert string to enum, but when enum type is only, var castTo = fieldInfo.PropertyType.GetType(); //returns a Type object, e.g. MyEnum var parsedEnum = (castTo) Enum.Parse(castTo, valueFromSql); The problem is that compiler wouldn't accept a variable that contains a Type object....

Cast function A cast function takes a number and converts it to the target integer type. Syntax: int<N>(x); uint<N>(x); int(x); // Alias of int<32>(x); uint(x); // Alias of uint<32>(x); Note: even though an int doesn't have a fixed size, we use the 32 bit cast...

比如,我可能创建一堆的Box对象,传递的泛型的类型,可能是Integer、Float、Double、Long或者Number类型,虽然可以统一用通配符?一招解决,但同样会存在String类型的泛型也会被接受。 我现在不想String或者其他非数字类型的Box去执行showBox的方法,这时会发现Integer、Float、Double、Long都有统一的父类Number,那么就可以使用上...
