TimeSpan.MaxValue 字段
表示最大的 TimeSpan 值。此字段为只读。
**命名空间:**System
**程序集:**mscorlib（在 mscorlib.dll 中）
语法
声明
Public Shared ReadOnly MaxValue As TimeSpan
用法
Dim value As TimeSpan
value = TimeSpan.MaxValue
public static readonly TimeSpan MaxValue
public:
static initonly TimeSpan MaxValue
public static final TimeSpan MaxValue
public static final var MaxValue : TimeSpan
备注
此字段的值等效于 Int64.MaxValue 刻度数。此值的字符串表示形式为 +10675199.02:48:05.4775807。
示例
下面的代码示例引用并显示 MaxValue 字段的值。
