1.安装
安装office，需要使用其中的dll，或者直接使用下面的dll
2.引用
添加此dll引用到项目中，并且嵌入互操作类型设置为false,否则代码中使用MSProject.ApplicationClass 会报错
3.读取demo：
public ActionResult Import(HttpPostedFileBase file)
{
Microsoft.Office.Interop.MSProject.ApplicationClass prj = new MSProject.ApplicationClass();
string prjFileName = file.FileName;
prjFileName= @"C:\Users\Administrator\Desktop\" + prjFileName + "";
prj.FileOpen(prjFileName, true, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, MSProject.PjPoolOpen.pjPoolReadOnly, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
foreach (MSProject.Project proj in prj.Projects)
{
foreach (MSProject.Task task in proj.Tasks)
{
string str = "";
int iTaskLevel = task.OutlineLevel;
for (int j = 0; j < iTaskLevel; j++)
{
str += "---";
}
Response.Write(str + task.Name + "++++++" + task.Start + "+++++" + task.Finish + task.ResourceNames.ToString() + "<br/>");
}
}
prj.FileClose(MSProject.PjSaveType.pjDoNotSave, false);
prj.Quit(MSProject.PjSaveType.pjDoNotSave);
return Json("");
}
