Lesen Sie nur oder Sperren Sie die Zellen oder Zeilen, die Verwendung von open xml sdk

Habe ich gemäß den folgenden link Excel-Datei Passwort-Schutz mit dem Open XML SDK.

Hier gab ich Ihnen die volle code zum öffnen der Datei aus dem Verzeichnis und Zellen einfügen. Hier habe ich schon eingefügt, nur eine Zelle. Sie können einfügen, wie Sie wollen. Hier habe ich eingefügt gesperrten Zellen. Finde diese eine, es wird sehr hilfreich für Sie..

Hinweis : die Hier, die ich erwähnt habe den code nur zum Lesen der vorhandenen Datei einfügen und die Zeilen-und Zellen und Schloss die Zellen wurden manuell eingefügt

Danke.
