Type.GetArrayRank Type.GetArrayRank Type.GetArrayRank Type.GetArrayRank Method

定義

取得陣列中的維度數目。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

傳回

包含目前類型中之維度數目的整數。An integer that contains the number of dimensions in the current type.

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。The functionality of this method is unsupported in the base class and must be implemented in a derived class instead.

目前的類型不是陣列。The current type is not an array.

範例

下列範例會顯示在陣列中的維度數目。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("Message: " + e.Message);
