DataTypeInfo.TypeEnumName プロパティ

定義

名前空間:

Microsoft.SqlServer.Dts.Runtime

アセンブリ:

Microsoft.SqlServer.ManagedDTS.dll

データ型のシンボリック名を返します。 このフィールドは読み取り専用です。

public:
 property System::String ^ TypeEnumName { System::String ^ get(); };

public string TypeEnumName { get; }

member this.TypeEnumName : string

Public ReadOnly Property TypeEnumName As String

プロパティ値

String

データ型のシンボリック名を表す文字列です。

例

次のコード例では、コレクションを反復処理し、SQL Server Integration Services (SSIS) の各データ型を出力TypeEnumNameTypeName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);  
            }  
        }  
    }  
}

            'Create the DataTypeInfos collection.

            '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
