示例

以下示例列举了计算机上可用数据库提供者的属性。

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  

示例输出：

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
