member this.Current : Microsoft.SqlServer.Dts.Runtime.LogEntryInfo

Public ReadOnly Property Current As LogEntryInfo

Property Value

Gets the current LogEntryInfo element in the collection.

Examples

The following code sample creates an enumerator, and then uses the Current, MoveNext, and Reset methods to navigate over the collection.

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

namespace LogEntryInfosTest  
{  
    class Program  
    {  
        static void Main(string[] args)  
        {  
            // The package is one of the SSIS Samples.  
            string mySample = @"C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx";  

            // Create the Application, and load the sample.  
            Application app = new Application();  
            Package pkg = app.LoadPackage(mySample, null);  

            //Create the Enumerator.  
            LogEntryInfos leInfos = pkg.LogEntryInfos;  
            LogEntryInfoEnumerator myEnumerator = leInfos.GetEnumerator();  
            Console.WriteLine("The collection contains the following values:");  
            int i = 0;  
            while ((myEnumerator.MoveNext()) && (myEnumerator.Current != null))  
                Console.WriteLine("[{0}] {1}", i++, myEnumerator.Current);  

            Console.WriteLine();  
        }  
    }  
}

            ' Create the Application, and load the sample.  
            Dim app As Application =  New Application()   
            Dim pkg As Package =  app.LoadPackage(mySample,Nothing)   

            'Create the Enumerator.  
            Dim leInfos As LogEnTryInfos =  pkg.LogEnTryInfos   
            Dim myEnumerator As LogEnTryInfoEnumerator =  leInfos.GetEnumerator()   
            Console.WriteLine("The collection contains the following values:")  
            Dim i As Integer =  0   
            While (myEnumerator.MoveNext()) &&(myEnumerator.Current <> Nothing)  
            Console.WriteLine("[{0}] {1}",i = Console.WriteLine("[{0}] {1}",i + 1  
            End While  

            Console.WriteLine()  
        End Sub  
    End Class  
End Namespace  

Sample Output:

The collection contains the following values:

[0] Microsoft.SqlServer.Dts.Runtime.LogEntryInfo

Remarks

After an enumerator is created, or after a call to the Reset method, the MoveNext method must be called to advance the enumerator to the first element of the collection before the enumerator can read the value of the Current property; otherwise, Current is undefined and throws an exception.

Current also throws an exception if the last call to MoveNext returned false, which indicates the end of the collection.

Current does not move the position of the enumerator, and consecutive calls to Current return the same object until either MoveNext or Reset is called.

An enumerator remains valid as long as the collection remains unchanged. If changes are made to the collection, such as adding, modifying, or deleting elements, the enumerator is invalidated and becomes irrecoverable; thus, the next call to MoveNext or Reset throws an InvalidOperationException. If the collection is modified between calls to MoveNext and Current, Current returns the element that it is set to, even if the enumerator has been invalidated.
