屬性值

A LogProviderInfo object.

備註

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

範例

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

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;

namespace LogProvInfoProperties
{
    class Program
    {
        static void Main(string[] args)
        {
        Application app = new Application();
        LogProviderInfos infos = app.LogProviderInfos;

        //Using the Item method syntax of [x], obtain the first entry.
        LogProviderInfo lInfo = infos[0];
        String nameOfFirstItem = infos[0].Name;

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

Imports System.Collections.Generic
Imports System.Text
Imports Microsoft.SqlServer.Dts.Runtime
 
Namespace LogProvInfoProperties
    Class Program
        Shared  Sub Main(ByVal args() As String)
        Dim app As Application =  New Application() 
        Dim infos As LogProviderInfos =  app.LogProviderInfos 
 
        'Using the Item method syntax of [x], obtain the first entry.
        Dim lInfo As LogProviderInfo =  infos(0) 
        Dim nameOfFirstItem As String =  infos(0).Name 
 
        'Print the name of the log provider object located at position [0].
        Console.WriteLine("The ID of the first log provider is: {0}", lInfo.ID)
        Console.WriteLine("The Name of the first log provider is: {0}", nameOfFirstItem)
        End Sub
    End Class
End Namespace

Sample Output:

The ID of the first log provider is: {59B2C6A5-663F-4C20-8863-C83F9B72E2EB}

The Name of the first log provider is: SSIS log provider for Text files
