TimeSpan.Days 属性
获取由当前 TimeSpan 结构表示的整天数。
**命名空间:**System
**程序集:**mscorlib（在 mscorlib.dll 中）
语法
声明
Public ReadOnly Property Days As Integer
用法
Dim instance As TimeSpan
Dim value As Integer
value = instance.Days
public int Days { get; }
public:
property int Days {
int get ();
}
/** @property */
public int get_Days ()
public function get Days () : int
属性值
此实例的天数部分。返回值可以是正数也可以是负数。
备注
TimeSpan 值可以表示为 [-]d.hh:mm:ss.ff，其中减号是可选的，它指示负时间间隔，d 分量表示天，hh 表示小时（24 小时制），mm 表示分钟，ss 表示秒，而 ff 为秒的小数部分。Days 属性的值是表示天的分量 (d)。
示例
下面的代码示例创建几个 TimeSpan 对象并显示每个对象的 Days 属性。
