下午,所以我在这个问题上待了好几个小时,无法真正克服最后一个困难。以下是我正在编写的该程序的代码:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Diagnostics;
using System.Data;
using System.Data.SqlClient;
using System.Configuration;
namespace Test
{
class Program
{
static void Main()
{
EventLog alog = new EventLog();
alog.Log = "Application";
alog.MachineName = ".";
foreach (EventLogEntry entry in alog.Entries)
{
SqlConnection connection1 = new SqlConnection(@"Data Source=.\sqlexpress;Initial Catalog=syslog2;Integrated Security=True");
SqlDataAdapter cmd = new SqlDataAdapter();
cmd.InsertCommand = new SqlCommand("INSERT INTO Application VALUES (@EventLog, @TimeGenerated, @EventType, @SourceName, @ComputerName, @InstanceId, @Message) ");
cmd.InsertCommand.Parameters.Add("@EventLog",SqlDbType.VarChar).Value = alog.Log;
cmd.InsertCommand.Parameters.Add("@TimeGenerated", SqlDbType.DateTime).Value = entry.TimeGenerated;
cmd.InsertCommand.Parameters.Add("@EventType", SqlDbType.VarChar).Value = entry.EntryType;
cmd.InsertCommand.Parameters.Add("@SourceName", SqlDbType.VarChar).Value = entry.Source;
cmd.InsertCommand.Parameters.Add("@ComputerName", SqlDbType.VarChar).Value = entry.MachineName;
cmd.InsertCommand.Parameters.Add("@InstanceId", SqlDbType.VarChar).Value = entry.InstanceId;
cmd.InsertCommand.Parameters.Add("@Message", SqlDbType.VarChar).Value = entry.Message;
connection1.Open();
cmd.InsertCommand.ExecuteNonQuery();
connection1.Close();
}
}
}
}
该代码可以正常编译,没有错误或警告,但是当我运行它时,只要它到达cmd.InsertCommand.ExecuteNonQuery();就可以了。我收到以下错误:
ExecuteNonQuery:连接属性尚未初始化。
关于我错过的任何想法?
