'使用
Dim instance As DataTypeInfo
Dim value As String
value = instance.TypeName
public string TypeName { get; }
public:
property String^ TypeName {

プロパティ値
型: System.String
データ型の長い説明を表す文字列です。
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);
}
}
}
}

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);
