forループの代わりにforeachループを使用してください-これで私の問題は解決しました。
int j = 0;
foreach (Microsoft.Office.Interop.Word.Page p in pane.Pages)
{
var bits = p.EnhMetaFileBits;
var target = path1 +j.ToString()+ "_image.doc";
try
{
using (var ms = new MemoryStream((byte[])(bits)))
{
var image = System.Drawing.Image.FromStream(ms);
var pngTarget = Path.ChangeExtension(target, "png");
image.Save(pngTarget, System.Drawing.Imaging.ImageFormat.Png);
}
}
catch (System.Exception ex)
{
MessageBox.Show(ex.Message);
}
j++;
}
これは私のために働いたプログラムの修正です。PDFとして保存アドインがインストールされたWord 2007を使用します。.docファイルのディレクトリを検索し、Wordで開き、PDFとして保存します。Microsoft.Office.Interop.Wordへの参照をソリューションに追加する必要があることに注意してください。
