Type.GetArrayRank メソッド

定義

配列の次元数を取得します。Gets the number of dimensions in an array.

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

戻り値

現在の型の次元数である整数。An integer that contains the number of dimensions in the current type.

実装

例外

このメソッドの機能は、基底クラスではサポートされていないため、代わりに派生クラスで実装する必要があります。The functionality of this method is unsupported in the base class and must be implemented in a derived class instead.

現在の型は配列ではありません。The current type is not an array.

次の例では、配列の次元数を表示します。The following example displays the number of dimensions in an array.

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
        {
            int[,,] myArray = new int[,,] {{{12,2,35},{300,78,33}},{{92,42,135},{30,7,3}}};
            Type myType = myArray.GetType();

            Console.WriteLine("Contents of myArray: {{{12,2,35},{300,78,33}},{{92,42,135},{30,7,3}}}");
            Console.WriteLine("myArray has {0} dimensions.", myType.GetArrayRank());
        }
        catch(NotSupportedException e)
        {
            Console.WriteLine("NotSupportedException raised.");
            Console.WriteLine("Source: " + e.Source);
            Console.WriteLine("Message: " + e.Message);
        }
        catch(Exception e)
        {
            Console.WriteLine("Exception raised.");
            Console.WriteLine("Source: " + e.Source);
            Console.WriteLine("Message: " + e.Message);
        }
