本文介绍了一个基于ASP.NET的应用程序，该程序可以搜索指定类别下的Word文档，并根据用户提供的关键字筛选文件名和文档内容。文章详细展示了aspx页面设计、aspx.cs后台逻辑处理，包括如何使用Word.Application组件来遍历和搜索文档。

二。aspx 文件：

<%...@ Page Language="C#" AutoEventWireup="true" CodeFile="word.aspx.cs" Inherits="word" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</head>

<body>

<div>

类别：<asp:TextBox ID="txtClass" runat="server"></asp:TextBox><br />

  文件名含有关键字<asp:TextBox ID="txtFileNameKey" runat="server"></asp:TextBox><br />

文档中含有关键字<asp:TextBox ID="txtFileContentKey" runat="server"></asp:TextBox> <br />

 <asp:Button ID="btnSearch" runat="server" OnClick="Button2_Click" Text="search" />

<asp:Label ID="txtContent" runat="server"></asp:Label><br />

</div>

</form>

</body>

</html>

三。aspx.cs 文件：

protected void Button2_Click(object sender, EventArgs e)

...{

search(txtClass.Text,txtFileNameKey.Text,txtFileContentKey.Text);

}

/**//// <summary>

/// 搜索

/// </summary>

/// <param name="strClass">类别，即表示搜索范围的根(大)文件夹（相对网站根目录）</param>

/// <param name="fileNameKey">文件名含有的关键字</param>

/// <param name="strFileContentKey">所有文档内要查找的关键字</param>

protected void search(string strClass,string fileNameKey,string strFileContentKey)

...{

Word.Application app = new ApplicationClass();

fileNameKey = "*" + fileNameKey + "*" + ".doc";

strClass = Server.MapPath("/ ") + strClass;//获取类别所在的绝对路径

GetFileNameList(strClass,fileNameKey);

//GetFileNameList(strClass);

string[] fileNameSet =new string[al.Count];//动态创建遍历过的文件的虚拟地址的集合

al.CopyTo(fileNameSet,0);

foreach(string str in fileNameSet )

...{

SearchKeyInFileContent(str,strFileContentKey,app);

}

if (WordContent != "")

...{

txtContent.Text = WordContent;

}

else

txtContent.Text = "对不起，找不到，建议您改变搜索条件";

object originalFormat = Missing.Value;

object routeDocument = Missing.Value;

object saveChanges = WdSaveOptions.wdDoNotSaveChanges;

app.Quit(ref saveChanges, ref originalFormat, ref routeDocument);//退出WINWORD进程

app = null;

GC.Collect();

//KillWordProcess();

}

/**//// <summary>

/// 查找函数

/// </summary>

/// <param name="strfile">文件名</param>

/// <param name="strFileContentKey">要查找的关键字</param>

/// <param name="app">要用哪个application打开</param>

protected void SearchKeyInFileContent(string strfile,string strFileContentKey,Application app)

...{

//object saveChanges = WdSaveOptions.wdDoNotSaveChanges;

app.DisplayAlerts = 0; //防止Word产生任何可能的提示信息

try

...{

object IsreadOnly = true;

object fileName=Request.MapPath(strfile);

object optional = Missing.Value;

object isvisible = false;

if (File.Exists(fileName.ToString()))//如果文件存在

...{

Word.Document doc = app.Documents.Open(

ref fileName, ref optional, ref IsreadOnly,

ref optional, ref optional, ref optional,

ref isvisible, ref optional, ref optional,

ref optional);

object MissingValue = Type.Missing;

int i = 0, iCount = 0;

Word.Find wfnd;

if (doc.Paragraphs != null && doc.Paragraphs.Count > 0)

...{

iCount = doc.Paragraphs.Count;

for (i = 1; i <= iCount; i++)

...{

wfnd = doc.Paragraphs[i].Range.Find;

wfnd.ClearFormatting();

wfnd.Text = strFileContentKey;

if (wfnd.Execute(ref MissingValue, ref MissingValue,

ref MissingValue, ref MissingValue,

ref MissingValue))//文档存在关键字，即有找到

...{

string strFileName = Convert.ToString(fileName);

int Severehost = Server.MapPath("/ ").Length;

strFileName = strFileName.Substring(Severehost);//取相对路径

WordContent += "<a href=" + """ + strFileName + """ + ">" + strFileName + "</a><br />";

doc.Close(ref MissingValue, ref MissingValue, ref MissingValue);//关闭当前文档，但并没并闭word程序，即进程WINWORD没关

break;//分段查询，有找到马上跳出，不用再找

}

catch

...{

}

finally

...{

}

/**//// <summary>

/// 获得文件列表

/// </summary>

/// <param name="strDI">父目录 </param>

/// <param name="strFileNameKey">文件名关键字</param>

public void GetFileNameList(string strDI,string strFileNameKey)

...{

DirectoryInfo di = new DirectoryInfo(strDI);

try

...{

string strfileName;

foreach (FileInfo fi in di.GetFiles(strFileNameKey))

...{

strfileName = di.ToString() + "/" + fi.Name.ToString();

strfileName = strfileName.Substring(19);

al.Add(strfileName); //this.globalmessage.Text += "<a href=" + """ + strfileName + """ + ">" + strfileName + "</a><br />";

}

catch

...{

}

try

...{

foreach (System.IO.DirectoryInfo di1 in di.GetDirectories())

...{

string strSonDirectoryInfo = di.ToString() + '/' + di1.Name;

GetFileNameList(strSonDirectoryInfo, strFileNameKey);

}

catch

...{

}

四：运行结果：
