Type.GetArrayRank 方法

定义

命名空间:

System

程序集:

System.Runtime.dll

Source:

Type.cs

获取数组中的维数。

public:
 virtual int GetArrayRank();

public virtual int GetArrayRank ();

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

Public Overridable Function GetArrayRank () As Integer

返回

Int32

包含当前类型中维数的整数。

例外

NotSupportedException

此方法的功能在基类中不受支持，并且必须改为在派生类中实现。

ArgumentException

当前类型不是数组。

示例

以下示例显示数组中的维度数。

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}}};
