Project文件读取：

方法1：Microsoft.Project.OLEDB.11.0

string strConn = "Provider=Microsoft.Project.OLEDB.11.0;Project Name=" + fileName;
DataSet ds = new DataSet();
using (OleDbConnection conn = new OleDbConnection(strConn))
{
conn.Open();
string[] tablesName = new string[] { "Assignments", "Tasks", "Resource" };
for (int k = 0; k < tablesName.Length; k++)
{
string strTableName = tablesName[k];
string str = "select * from " + strTableName;
OleDbDataAdapter da = new OleDbDataAdapter(str, conn);
da.Fill(ds, strTableName.ToLower());
da.Dispose();
}
conn.Close();
conn.Dispose();
}
return ds;

方法2：Microsoft.Office.Interop.MSProject

Object missing = Type.Missing;
ApplicationClass prj = new ApplicationClass();
//打开mpp文件
prj.FileOpen(fileName, true, missing, missing, missing, missing, missing, missing, missing,
missing, missing, PjPoolOpen.pjPoolReadOnly, missing, missing, missing, missing);
return prj.Projects;
以上两个方法都需要安装Microsoft.Project

方法3：mpxj

ProjectReader reader = ProjectReaderUtility.getProjectReader(fileName);
ProjectFile projectFile = reader.read(fileName);
List tasks = projectFile.getAllTasks();
for (int i = 0; i < tasks.size(); i++)
{
Task task = tasks.get(i) as Task;
}
