屬性值

A DBProviderInfos object.

備註

If the call to Contains method returns true, you can access the specified element in the collection by using the syntax DBProviderInfos[index]. If the Contains returns false, this property will throw an exception. In C#, this property is the indexer for the DBProviderInfos class.

範例

The following code example retrieves an item from the collection using two methods. The first method uses the dbprovInfos[0] syntax to retrieve the entire object located in the first position of the collection and place it in the dbInfo object. You can now retrieve all properties from the dbInfo object as usual. The second method demonstrates how to retrieve a specific property from the first object in the collection.

namespace DBProvInfos_GetEnum
{
    class Program
    {
        static void Main(string[] args)
        {
            Application app = new Application();
            DBProviderInfos dbprovInfos = app.DBProviderInfos;

            //Using the Item method syntax of [x], obtain the first entry.
            DBProviderInfo dbInfo = dbprovInfos[0];
            String nameOfFirstItem = dbprovInfos[0].Name;

            //Print the name of the log provider object located at position [0].
            Console.WriteLine("The db provider type of the first provider is: {0}", dbInfo.ProviderType);
            Console.WriteLine("The Name of the first database provider is: {0}", nameOfFirstItem);
        }
    }

            Dim dbprovInfos As DBProviderInfos =  app.DBProviderInfos 
 
            'Using the Item method syntax of [x], obtain the first entry.
            Dim dbInfo As DBProviderInfo =  dbprovInfos(0) 
            Dim nameOfFirstItem As String =  dbprovInfos(0).Name 
 
            'Print the name of the log provider object located at position [0].
            Console.WriteLine("The db provider type of the first provider is: {0}", dbInfo.ProviderType)
            Console.WriteLine("The Name of the first database provider is: {0}", nameOfFirstItem)
        End Sub
