我用的是vs2005,c#做的

读文件属性代码: 添加引用,microsoft shell controls and automation

using Shell32;

string sFileType = ""; //2
string sFileAuthor = ""; //9
string sFileTitle = ""; //10
string sFileSubject = ""; //11
string sFileCategory = ""; //12
string sFileComment = ""; //14

ShellClass sh = new ShellClass();
Folder dir1 = sh.NameSpace(Path.GetDirectoryName(filepath));
FolderItem item = dir1.ParseName(Path.GetFileName(filepath));

sFileType = dir1.GetDetailsOf(item, 2);
sFileAuthor = dir1.GetDetailsOf(item, 9);
sFileTitle = dir1.GetDetailsOf(item, 10);
sFileSubject = dir1.GetDetailsOf(item, 11);
sFileCategory = dir1.GetDetailsOf(item, 12);
sFileComment = dir1.GetDetailsOf(item, 14);

写文件属性

1. 下载dsofile.dll,你也可以在微软网站上搜索下载,放入system32文件夹下,开始菜单,运行,输入cmd 进入到system32目录下 输入regsvr32 dsofile.dll,注册组建,然后添加引用

DSOFile.OleDocumentProperties dso = new DSOFile.OleDocumentProperties();
dso.Open(path, false, DSOFile.dsoFileOpenOptions.dsoOptionUseMBCStringsForNewSets);

dso.SummaryProperties.Title = "";
dso.SummaryProperties.Subject = "";
dso.SummaryProperties.Author = "";
dso.SummaryProperties.Comments = "";

dso.Save();
dso.Close(false);
