Type.GetArrayRank 方法

获取 Array 中的维数。

**命名空间:**System
**程序集:**mscorlib（在 mscorlib.dll 中）

语法

声明
Public Overridable Function GetArrayRank As Integer
用法
Dim instance As Type
Dim returnValue As Integer

returnValue = instance.GetArrayRank

public virtual int GetArrayRank ()

public:
virtual int GetArrayRank ()

public int GetArrayRank ()

public function GetArrayRank () : int

返回值

包含当前 Type 中维数的 Int32。

异常

异常类型	条件
NotSupportedException	此方法的功能在基类中不受支持，而必须在派生类中实现。
ArgumentException	当前 Type 不是数组。

示例

下面的示例显示数组中的维数。
