TypeName プロパティ

構文

'宣言
Public ReadOnly Property TypeName As String
    Get
'使用
Dim instance As DataTypeInfo
Dim value As String

value = instance.TypeName

public string TypeName { get; }

public:
property String^ TypeName {
    String^ get ();
}

member TypeName : string

function get TypeName () : String

説明

データ型の長い名前を返します。たとえば、DT_CY 型に対して currency を返します。

使用例

次のコード例では、コレクションに対する繰り返し処理を実行し、SQL Server Integration Services (SSIS) の各データ型の TypeEnumName と TypeName を出力します。

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;

namespace DataTypeInfo_Properties
{
    class Program
    {
        static void Main(string[] args)
        {
            //Create the DataTypeInfos collection.
            DataTypeInfos dataInfos = new Application().DataTypeInfos;

            //Iterate over the collection, printing the values
            //of the properties.
            foreach (DataTypeInfo dInfo in dataInfos)
            {
                Console.WriteLine("TypeName: {0}, TypeEnumName: {1}", dInfo.TypeName, dInfo.TypeEnumName);
                //Console.WriteLine("TypeEnumName   {0}", dInfo.TypeEnumName);
            }
        }
    }
}

Imports System
Imports System.Collections.Generic
Imports System.Text
Imports Microsoft.SqlServer.Dts.Runtime
 
Namespace DataTypeInfo_Properties
    Class Program
        Shared  Sub Main(ByVal args() As String)
            'Create the DataTypeInfos collection.
            Dim dataInfos As DataTypeInfos =  New Application().DataTypeInfos 
 
            'Iterate over the collection, printing the values
            'of the properties.
            Dim dInfo As DataTypeInfo
            For Each dInfo In dataInfos
                Console.WriteLine("TypeName: {0}, TypeEnumName: {1}", dInfo.TypeName, dInfo.TypeEnumName)
                'Console.WriteLine("TypeEnumName   {0}", dInfo.TypeEnumName);
            Next
         End Sub
    End Class
End Namespace
