Type.GetArrayRank Метод

Определение

Пространство имен:

System

Сборка:

System.Runtime.dll

Исходный код:

Type.cs

Возвращает размерность массива.

public:
 virtual int GetArrayRank();

public virtual int GetArrayRank ();

abstract member GetArrayRank : unit -> int
override this.GetArrayRank : unit -> int

Public Overridable Function GetArrayRank () As Integer

Возвращаемое значение

Int32

Целое число, указывающее на количество измерений текущего типа.

Исключения

NotSupportedException

Функциональность этого метода не поддерживается в базовом классе и должна быть реализована в производном классе.

ArgumentException

Текущий тип не является массивом.

Примеры

В следующем примере показано количество измерений в массиве.

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 );
   }

}
