如何组织重复代码？

Question

代码看起来如下：

1）我有一些图片：

var imageIds = caseStudyPage.Images; 
foreach (var imageId in imageIds) 
{ 
    byte[] csImage = GetImage(imageId); 
} 

2），我有结构如下：

var document = new Document(); 
document 
    .AddField(new TextField("CS Counter Basic Name", "Case Study")) 
    .AddField(new TextField("CS Counter Number", _numberInParentDocument.ToString())) 
    .AddField(new TextField("Page Title", caseStudyPage.Page_Title)) 
    .AddField(new TextField("Common Footer Text 1", commonFooterText1)) 
    .AddField(new TextField("Page Title Content", caseStudyPage.Page_Title)) 
    .AddTable(new Table("Images") 
     .AddRow(new TableRow().AddField(new ImageField("Image", imageBytes, ImageType.Jpeg)) 
      .AddField(new TextField("Overview", caseStudyPage.Overview)) 
      .AddField(new TextField("Engagement", caseStudyPage.Engagement)) 
      .AddField(new TextField("Publish Date", caseStudyPage.Publish_Date.ToString("MMM. dd, yyyy"))) 
    .AddField(new TextField("Common Footer Text 2", commonFooterText2)))); 

我需要把文档结构从2）从1）的循环内部，以设置ImageField的imageBytes变量，但文档应该只有一个。我不知道循环只有这部分如何：

.AddRow(new TableRow().AddField(new ImageField("Image", imageBytes, ImageType.Jpeg)) 

Answer 1

var document = new Document(); 
document 
    .AddField(new TextField("CS Counter Basic Name", "Case Study")) 
    .AddField(new TextField("CS Counter Number", _numberInParentDocument.ToString())) 
    .AddField(new TextField("Page Title", caseStudyPage.Page_Title)) 
    .AddField(new TextField("Common Footer Text 1", commonFooterText1)) 
    .AddField(new TextField("Page Title Content", caseStudyPage.Page_Title)); 

var table = new Table("Images"); 
foreach (var imageId in imageIds) 
{ 
    byte[] csImage = GetImage(imageId); 
    table.AddRow(new TableRow().AddField(new ImageField("Image", csImage, ImageType.Jpeg)) 
      .AddField(new TextField("Overview", caseStudyPage.Overview)) 
      .AddField(new TextField("Engagement", caseStudyPage.Engagement)) 
      .AddField(new TextField("Publish Date", caseStudyPage.Publish_Date.ToString("MMM. dd, yyyy"))); 
} 

document.AddTable(table); 
document.AddField(new TextField("Common Footer Text 2", commonFooterText2))));
