引入var是一把双刃剑,一方面简化了代码,但是同时可能影响了可读性,特别是那些你不熟悉的类型。为此Stuart W. Marks给出了一份使用指南Style Guidelines for Local Variable Type Inference inJava。其主要观点如下: 主要原则 阅读代码比编写代码更重要 使用var应当让读者能够清楚推断出类型 代码可读性不应该依赖于IDE ...

Using type inference tells the compiler to take the type on the right hand side, and use that type for the variable. It specifically does not mean VARIANT, or Object. The variables are strongly typed; the only difference is that the compiler is able to deduce the type from the initializer...

Type inference can be used only for non-static local variables; it cannot be used to determine the type of class fields, properties, or functions. Local type inference applies at procedure level. It cannot be used to declare variables at module level (within a class, structure, module, or ...
With type inference "turned on", the above statement gives x the type integer. It is as if you had explicitly declared the type of x to be integer, but instead the compiler is doing that for you. Turn it on, turn it off In the LINQ May 2005 CTP, type inference was on all the ...
