C# 使用Open XML SDK将幻灯片从一个演示文稿复制到另一个演示文稿,c#,ms-office,powerpoint,openxml,openxml-sdk,C#,Ms Office,Powerpoint,Openxml,Openxml Sdk,对不起，我的英语：）有一个密码 using (var sourceDoc = PresentationDocument.Open(@"d:\source.pptx", false)) { using (var destDoc = PresentationDocument.Open(@"d:\dest.pptx", true)) { } } 我尝试复制幻灯片№2从sourceDoc粘贴到destDoc位置4。有些文章有相同的标题和标题，但不幸的是我不能应用。我只是

对不起，我的英语：）

有一个密码

using (var sourceDoc = PresentationDocument.Open(@"d:\source.pptx", false))
{
    using (var destDoc = PresentationDocument.Open(@"d:\dest.pptx", true))
    {

    }
}

我尝试复制幻灯片№2从
sourceDoc
粘贴到
destDoc
位置4。

有些文章有相同的标题和标题，但不幸的是我不能应用。我只是糊涂了。例如：

uniqueId = GetMaxIdFromChild(destPresPart.Presentation.SlideMasterIdList);

什么意思？编译时说错误
