Microsoft.VisualC.STLCLR.dll 测试容器中是否没有元素。 C# publicboolempty(); 返回 Boolean 如果容器中没有元素,则为true;否则为false。 注解 有关详细信息,请参阅vector::empty (STL/CLR)。 适用于 产品版本 .NET Framework3.5, 4.0, 4.5, 4.5.1, 4.5.2, 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, 4.7...
It deletes the rest of the elements using a different form of erase and then displays the vector (now empty) again. The ShowVector routine uses the empty function to determine whether to generate the contents of the vector.Exampleคัดลอก ...
