範例
This enumeration is used by the DBProviderInfo class in the ProviderSubType property. The following example enumerates the properties of the database providers available on the computer, including the ProviderSubType which returns a value from this enumeration.
namespace dbproviderinfo
{
class Program
{
static void Main(string[] args)
{
Application app = new Application();
DBProviderInfos dbis = app.DBProviderInfos;
foreach (DBProviderInfo dbi in dbis)
{
Console.WriteLine("Description = {0}, Name = {1}, ParseName = {2}", dbi.Description, dbi.Name, dbi.ParseName);
Console.WriteLine("ProviderSubType ={0}, ProviderType = {1}", dbi.ProviderSubType, dbi.ProviderType);
Console.WriteLine("SupportsNullColumns = {0}, UseFullTableName = {1}", dbi.SupportsNullColumns, dbi.UseFullTableName);
}
}
}
}
Namespace dbproviderinfo
Class Program
Shared Sub Main(ByVal args() As String)
Dim app As Application = New Application()
Dim dbis As DBProviderInfos = app.DBProviderInfos
Dim dbi As DBProviderInfo
For Each dbi In dbis
Console.WriteLine("Description = {0}, Name = {1}, ParseName = {2}", dbi.Description, dbi.Name, dbi.ParseName)
Console.WriteLine("ProviderSubType ={0}, ProviderType = {1}", dbi.ProviderSubType, dbi.ProviderType)
Console.WriteLine("SupportsNullColumns = {0}, UseFullTableName = {1}", dbi.SupportsNullColumns, dbi.UseFullTableName)
Next
End Sub
End Class
End Namespace
Sample output:
Description = MediaCatalogDB OLE DB Provider, Name = MediaCatalogDB OLE DB Provider, ParseName = {09E767A6-4481-4791-86A5-A739E5290E4C}
ProviderSubType =None, ProviderType = OleDb
SupportsNullColumns = True, UseFullTableName = True
Description = Microsoft OLE DB Provider for SQL Server, Name = SQLOLEDB, ParseName = {0C7FF16C-38E3-11d0-97AB-00C04FC2AD98}
ProviderSubType =SqlServer, ProviderType = OleDb
SupportsNullColumns = True, UseFullTableName = True
