浅谈Try catch finally 与using

对于Try catch finally，大家应该都不陌生，您接触的写法可能会是下面的记几种类型：

Try catch (您可以匹配多个catch)

try

{

}

catch (Exception)

{

throw;

}

Try finally

try

{

}

finally

{

}

Try catch finally (同样，你一样可以匹配多个catch)

usingTry<?xml version="1.0" encoding="utf-8" ?>

至此，完成了一个加强版的using，和使用普通的using是一样的。
