3、页面调用代码：Test01.aspx.cs
View Code
1 public partial class test01 : System.Web.UI.Page
2 {
3 protected void Page_Load(object sender, EventArgs e)
4 {

6 }

8 protected void btnAction_Click(object sender, EventArgs e)
9 {
10 List<object[]> data = null;
11 EventLogSearch eventSearch = null;
12 EventLogEntryType[] eventEntryTypeEFilters = null;
13
14 try
15 {
16 eventEntryTypeEFilters = new EventLogEntryType[] {EventLogEntryType.Error};
17 eventSearch = new EventLogSearch();
18
19
20 gvShow.AllowPaging = true;
21 gvShow.PageSize = 10;
22 gvShow.DataSource = eventSearch.GetData(ddlType.SelectedValue, DateTime.Now.AddMonths(-2), true, eventEntryTypeEFilters);
23 gvShow.DataBind();
