Type.GetArrayRank 方法

定義

取得陣列中的維度數目。

public:
 abstract int GetArrayRank();
public:
 virtual int GetArrayRank();
public abstract int GetArrayRank ();
public virtual int GetArrayRank ();
abstract member GetArrayRank : unit -> int
abstract member GetArrayRank : unit -> int
override this.GetArrayRank : unit -> int
Public MustOverride Function GetArrayRank () As Integer
Public Overridable Function GetArrayRank () As Integer

傳回

Int32

包含目前類型中之維度數目的整數。

實作

例外狀況

這個方法的功能不受基底類別的支援,因此必須改為在衍生類別中實作。

目前的類型不是陣列。

範例

下列範例會顯示陣列中的維度數目。

using namespace System;
int main()
{
   try
   {
      array<Int32, 3>^myArray = gcnew array<Int32,3>(3,4,5);
      Type^ myType = myArray->GetType();
      Console::WriteLine( "myArray has {0} dimensions.", myType->GetArrayRank() );
   }
   catch ( NotSupportedException^ e ) 
   {
      Console::WriteLine( "NotSupportedException raised." );
      Console::WriteLine( "Source: {0}", e->Source );
      Console::WriteLine( "Message: {0}", e->Message );
   }
   catch ( Exception^ e ) 
   {
      Console::WriteLine( "Exception raised." );
      Console::WriteLine( "Source: {0}", e->Source );
      Console::WriteLine( "Message: {0}", e->Message );
   }

}
using System;

class MyArrayRankSample
{
    public static void Main()
    {
        try
        {
