c#.net中如何通过关键字检索指定文件夹中的word文档。

[zjianjie]

我是一名新手，最近碰到个关于检索的问题，就是想通过关键字检索指定文件夹中的word文档，并将含该关键字的文档标题显示在一个列表中，同时可以点击打开对应的word文档，希望得到大家的指点，谢谢！！

ps：是检索word文档中的内容。

以上代码可以用了,原来是我传的路径太长了,导致无法打开文件!

重发调试通过的代码:
/// <summary>
/// search in a DOC file(查询DOC文件的内容)
/// </summary>
/// <param name="fileName"></param>
/// <param name="searchForText">要搜索的文本</param>
/// <param name="CaseSensitive">是否区分大小写</param>
/// <returns></returns>
public static bool SearchInDoc(string fileName,string searchForText,bool CaseSensitive)
{
bool Result = (searchForText.Length == 0);
object filename = fileName; //要打开的文档路径
object MissingValue=System.Reflection.Missing.Value;//Type.Missing;
object readOnly = false;
Microsoft.Office.Interop.Word.Application wp = null;
Microsoft.Office.Interop.Word.Document wd = null;

try
{
wp = new Microsoft.Office.Interop.Word.ApplicationClass();
wd = wp.Documents.Open(ref filename,ref MissingValue,
ref readOnly,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue);

int i=0,iCount=0;
Microsoft.Office.Interop.Word.Find wfnd;

if (wd.Paragraphs != null && wd.Paragraphs.Count>0)
{
iCount = wd.Paragraphs.Count;
for(i=1;i<=iCount;i++)
{
wfnd=wd.Paragraphs[i].Range.Find;
wfnd.ClearFormatting();
wfnd.Text = searchForText;
if (wfnd.Execute(ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue))
{
Result = true;
break;
}
}
}
}
catch(Exception ex)
{
throw new Exception(ex.Message);
}
finally
{
if(wd != null)
{
wd.Close(ref nullobj,ref nullobj,ref nullobj);
System.Runtime.InteropServices.Marshal.ReleaseComObject(wd);
wd = null;
}

if(wp != null)
{
wp.Quit(ref nullobj,ref nullobj,ref nullobj);
System.Runtime.InteropServices.Marshal.ReleaseComObject(wp);
wp = null;
}

GC.Collect();
}

return Result;
}

关注中!我现在也在处理这问题,只是每次打开WORD文档就没反应了,也希望哪位朋友帮我看看代码是什么回事.

/// <summary>
/// search in a DOC file(查询DOC文件的内容)
/// </summary>
/// <param name="fileName"></param>
/// <param name="searchForText">要搜索的文本</param>
/// <param name="CaseSensitive">是否区分大小写</param>
/// <returns></returns>
public static bool SearchInDoc(string fileName,string searchForText,bool CaseSensitive)
{
bool Result = (searchForText.Length == 0);
object filename = fileName; //要打开的文档路径
object MissingValue=Type.Missing;
Microsoft.Office.Interop.Word.Application wp = new Microsoft.Office.Interop.Word.ApplicationClass();
wp.Visible = false;
Microsoft.Office.Interop.Word.Document wd = wp.Documents.Open(ref filename,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue);//运行到这句就没反应,结束word进程后,就出现"异常详细信息: System.Runtime.InteropServices.COMException: 远程过程调用失败。
"

int i=0,iCount=0;
Microsoft.Office.Interop.Word.Find wfnd;

if (wd.Paragraphs != null && wd.Paragraphs.Count>0)
{
iCount = wd.Paragraphs.Count;
for(i=1;i<=iCount;i++)
{
wfnd=wd.Paragraphs[i].Range.Find;
wfnd.ClearFormatting();
wfnd.Text = searchForText;

if (wfnd.Execute(ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue,ref MissingValue,
ref MissingValue))
{
Result = true;
break;
}
}
}

return Result;
}
