如果你的意思是在 pdf 文件中搜索，你可以这样做：

  • 下载此 dll Interop.Cisso.DLL，然后将其添加为参考
  • 创建您的目录（您应该在索引服务中定义一个目录以在其中搜索）它是通过这种方式完成的：http: //support.microsoft.com/kb/308202

  • 最后，这是您进行搜索的代码：

       DataSet ds = new DataSet("IndexServerResults");
    CissoQueryClass q = new CissoQueryClass();
    CissoUtilClass util = new CissoUtilClass();

    OleDbDataAdapter da = new OleDbDataAdapter();

string query = "";
if (lstSearchIntegration.SelectedValue == "-1") {
    query = "@all Contains " + txtKeywordOne.Text + " and not #filename *.log";
} else {
    string operation = "";
    if (lstSearchIntegration.SelectedValue.ToLower == "and") {
        operation = "and";
    } else {
        operation = "or";
    }
    query = "@all Contains " + txtKeywordOne.Text + " " + operation + " " + txtKeywordTwo.Text;

 }

switch (lstDocType.SelectedValue) {
    case "doc":
        query += " and #filename *.doc";
        break;
    case "pdf":
        query += " and #filename *.pdf";
        break;
    case "ppt":
        query += " and #filename *.ppt";
        break;
    case "pps":
        query += " and #filename *.pps";
        break;
}

q.Query = query;
q.Catalog = "YourCatalogName";
q.SortBy = "rank[d]";
q.Columns = "DocAppName,rank, path, size, FileName,VPath, Create";

q.MaxRecords = 1000;
    util.AddScopeToQuery(q, "YourFolder", "deep");
object obj = q.CreateRecordset("nonsequential");
da.Fill(ds, obj, "IndexServerResults");
DataTable mydt = new DataTable();
mydt = ds.Tables[0];

请注意：

  1. 我正在使用和/或操作进行更智能的搜索
  2. 我在 doc、pdf、ppt 和 pps 中搜索
  3. 我正在从搜索中排除日志文件

我可以推荐Aspose.PDF但它要花钱
