EventLogEntryCollection.Count 属性

获取事件日志中的项数（EventLogEntry 集合中的元素）。

**命名空间:**System.Diagnostics
**程序集:**System（在 system.dll 中）

语法

声明
Public ReadOnly Property Count As Integer
用法
Dim instance As EventLogEntryCollection
Dim value As Integer

value = instance.Count

public int Count { get; }

public:
virtual property int Count {
    int get () sealed;
}

/** @property */
public final int get_Count ()

public final function get Count () : int

属性值

当前在事件日志中的项数。

备注

EventLogEntryCollection 表示日志中所有项的动态列表。因此，Count 在您创建的 EventLogEntryCollection 实例的生存期内可以更改。通常最好直接使用 Count 属性，而不用将其值分配给变量。

示例

' Create a new EventLog object.
Dim myEventLog1 As New EventLog()
myEventLog1.Log = myLogName
' Obtain the Log Entries of the Event Log
Dim myEventLogEntryCollection As EventLogEntryCollection = myEventLog1.Entries
Console.WriteLine("The number of entries in 'MyNewLog' = " + _
                           myEventLogEntryCollection.Count.ToString())
' Display the 'Message' property of EventLogEntry.
Dim i As Integer
For i = 0 To myEventLogEntryCollection.Count - 1
   Console.WriteLine("The Message of the EventLog is :" + _
                  myEventLogEntryCollection(i).Message)
Next i

// Create a new EventLog object.
EventLog myEventLog1 = new EventLog();
myEventLog1.Log = myLogName;
// Obtain the Log Entries of the Event Log
EventLogEntryCollection myEventLogEntryCollection=myEventLog1.Entries;
Console.WriteLine("The number of entries in 'MyNewLog' = "+
                        myEventLogEntryCollection.Count);
// Display the 'Message' property of EventLogEntry.
for(int i=0;i<myEventLogEntryCollection.Count;i++)
{
   Console.WriteLine("The Message of the EventLog is :"+
                           myEventLogEntryCollection[i].Message);
}

// Create a new EventLog object.
EventLog^ myEventLog1 = gcnew EventLog;
myEventLog1->Log = myLogName;

// Obtain the Log Entries of the Event Log
EventLogEntryCollection^ myEventLogEntryCollection = myEventLog1->Entries;
Console::WriteLine( "The number of entries in 'MyNewLog' = {0}", myEventLogEntryCollection->Count );

// Display the 'Message' property of EventLogEntry.
for ( int i = 0; i < myEventLogEntryCollection->Count; i++ )
{
   Console::WriteLine( "The Message of the EventLog is : {0}", myEventLogEntryCollection[ i ]->Message );
}

// Create a new EventLog object.
EventLog myEventLog1 = new EventLog();

myEventLog1.set_Log(myLogName);

// Obtain the Log Entries of the Event Log
EventLogEntryCollection myEventLogEntryCollection = 
    myEventLog1.get_Entries();

Console.WriteLine("The number of entries in 'MyNewLog' = " 
    + myEventLogEntryCollection.get_Count());

// Display the 'Message' property of EventLogEntry.
for (int i = 0; i < myEventLogEntryCollection.get_Count(); i++) {
    Console.WriteLine("The Message of the EventLog is :" 
        + myEventLogEntryCollection.get_Item(i).get_Message());
}
