可能重复: ReSharper的和VAR
在我安装了整形它要求(通过警告),我用VAR只要有可能,例如:
After I have installed ReShaper it demands(by warnings) that I use var whenever possible, for example
UnhandledExceptionEventArgs ue = (UnhandledExceptionEventArgs) t;
ReSharper的希望把它变成
ReSharper wants to turn it into
var ue = (UnhandledExceptionEventArgs) t;
我喜欢的第一个版本好,是没有任何理由preFER变种?更好的性能?什么?或者是它只是一个code风格呢?
I like the first version better, is there any reason to prefer var? better performance? anything? or is it just a code style?
这真的只是一个编码风格。编译器生成完全相同的两个变种。
It's really just a coding style. The compiler generates the exact same for both variants.
