在ASP.NET中使用用户控件

引用Word组件 MSWORD.OLB
private void btnOK_Click(object sender, System.EventArgs e)
{
try
{
object Nothing=System.Reflection.Missing.Value;//调用默认参数

//取得Word文件保存路径
object filename=@tbPath.Text;
//object visible=false;
//创建一个名为WordApp的组件对象
Word.Application WordApp=new Word.ApplicationClass();
//创建一个名为WordDoc的文档对象
object missing = System.Reflection.Missing.Value;
Word.Document WordDoc=WordApp.Documents.Add(ref missing,ref missing,ref missing,ref missing);
//增加一表格
Word.Table table=WordDoc.Tables.Add(WordApp.Selection.Range,1,1,ref Nothing,ref Nothing);
//在表格第一单元格中添加自定义的文字内容
table.Cell(1,1).Range.Text=tbBody.Text;
//在文档空白地方添加文字内容
WordDoc.Paragraphs.Last.Range.Text="欢迎参加.NET学习！";
//将WordDoc文档对象的内容保存为DOC文档
WordDoc.SaveAs(ref filename,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing);
//关闭WordDoc文档对象
WordDoc.Close(ref Nothing, ref Nothing, ref Nothing);
//关闭WordApp组件对象
WordApp.Quit(ref Nothing, ref Nothing, ref Nothing);
//返回结果
lbResult.Text="文档路径：<a href='"+tbPath.Text+"'>"+tbPath.Text+"</a>(点击链接查看)<br>生成结果：成功！";
}
catch(Exception Ex)
{
string str = Ex.Message;
Response.Write(str);
}

引用Exel组件

//使用ADO.NET方式反问
private void btnAdo_Click(object sender, System.EventArgs e)

objConn.Close();
}
//使用自动化方式
private void btnAuto_Click(object sender, System.EventArgs e)

用户控件的使用
<table bgcolor="<%=strColor%>" width="100%" cellpadding="10" cellspacing="0">
public abstract class header : System.Web.UI.UserControl
{ public string strColor = "Red";
private void Page_Load(object sender, System.EventArgs e)
{
}
}

private void btnApply_Click(object sender, System.EventArgs e)
{
lbColor.Text = ddlColor.SelectedItem.Text;
//改变用户控件背景色
Header1.strColor = ddlColor.SelectedItem.Text;
}
