DTSLogEntryFrequency 枚举

定义

命名空间:

Microsoft.SqlServer.Dts.Runtime

程序集:

Microsoft.SqlServer.ManagedDTS.dll

提供用于帮助进行日志规划的信息。 您应选取与您要在任务中生成特定日志条目的频率最密切对应的提示信息。 包的用户要设置日志条目筛选时，此枚举属性可以帮助他们。 用户可以查看此属性，预先知道是否会出现大量特定类型的条目并进行相应地规划。

public enum class DTSLogEntryFrequency

public enum DTSLogEntryFrequency

type DTSLogEntryFrequency = 

Public Enum DTSLogEntryFrequency

继承

Enum

DTSLogEntryFrequency

字段

Consistent	1	记录条目的次数保持不变，与工作负荷不成比例。 例如，在任务的开始和结束时创建日志。
Occasional	0	有时记录该条目，通常是在特殊情况下。
Proportional	2	记录条目的次数与工作负荷成比例。

示例

下面的代码示例循环访问 LogEntryInfos 集合，然后打印每个 LogEntryInfo 找到的属性，包括 FrequencyHint从此枚举返回值。 代码示例演示如何设置 FrequencyHint 属性是只读的。

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";  

            Application app = new Application();  
            Package pkg = app.LoadPackage(mySample, null);  
            LogEntryInfos logInfos = pkg.LogEntryInfos;  

            Console.WriteLine("Number of log entries:  {0}", logInfos.Count.ToString());  
            foreach (LogEntryInfo logInfo in logInfos)  
            {  
                Console.WriteLine("CreationName:   {0}", logInfo.CreationName);  
                Console.WriteLine("Description:    {0}", logInfo.Description);  
                Console.WriteLine("FrequencyHint:  {0}", logInfo.FrequencyHint);  
                Console.WriteLine("ID:             {0}", logInfo.ID);  
                Console.WriteLine("Name:           {0}", logInfo.Name);  
            }  
        }  
    }  
}

Namespace LogEnTryInfosTest  
    Class Program  
        Shared  Sub Main(ByVal args() As String)  
            ' The package is one of the SSIS Samples.  
            Dim mySample As String =  "C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx"   

            Dim app As Application =  New Application()   
            Dim pkg As Package =  app.LoadPackage(mySample,Nothing)   
            Dim logInfos As LogEnTryInfos =  pkg.LogEnTryInfos   

            Console.WriteLine("Number of log entries:  {0}", logInfos.Count.ToString())  
            Dim logInfo As LogEnTryInfo  
            For Each logInfo In logInfos  
                Console.WriteLine("CreationName:   {0}", logInfo.CreationName)  
                Console.WriteLine("Description:    {0}", logInfo.Description)  
                Console.WriteLine("FrequencyHint:  {0}", logInfo.FrequencyHint)  
                Console.WriteLine("ID:             {0}", logInfo.ID)  
                Console.WriteLine("Name:           {0}", logInfo.Name)  
            Next  
        End Sub  
    End Class  
End Namespace  

示例输出：

日志条目数：1

CreationName：

说明：日志包诊断信息，例如最大并发可执行文件

FrequencyHint：一致

ID： {65F44252-EB0C-4CCB-ADE4-BA4AB86B4CF9}

名称：诊断
