所以我有这个功能：
公共静态 BaseList GetVersesByChapterVerseRanges（字符串翻译，BaseList 标准列表）{ BaseList returnValue = new BaseList();;
if(criteriaList.Count() > 0)
{
List<VerseMaster.BusinessLayer.Vers> queryList = new List<Vers>();
int bookId = criteriaList[0].Book.BookId;
int StartChapter = criteriaList[0].StartChapter;
int EndChapter = criteriaList[0].EndChapter;
int StartVerse = criteriaList[0].StartChapterStartVerse;
int EndVerse = criteriaList[0].EndChapterEndVerse;
var searchQuery = (from v in VerseMaster.BusinessLayer.Controller.Controller.VerseMasterEntities.Verses where v.Translation.ToLower().StartsWith(translation.ToLower()) && v.BookId == bookId && v.ChapterNumber >= StartChapter && v.ChapterNumber <= EndChapter && (v.ChapterNumber == StartChapter ? (v.VerseNumber >= StartVerse) : true) && (v.ChapterNumber == EndChapter ? (v.VerseNumber <= EndVerse) : true) orderby v.ChapterNumber, v.VerseNumber ascending select v);
for(int i = 1; i < criteriaList.Count(); i++)
{
bookId = criteriaList[i].Book.BookId;
StartChapter = criteriaList[i].StartChapter;
EndChapter = criteriaList[i].EndChapter;
StartVerse = criteriaList[i].StartChapterStartVerse;
EndVerse = criteriaList[i].EndChapterEndVerse;
VerseMaster.BusinessLayer.DataObjects.Helper.VerseSearchCriteria criteria = criteriaList[i];
searchQuery = (System.Linq.IOrderedQueryable<VerseMaster.BusinessLayer.Vers>)searchQuery.Concat(from v in VerseMaster.BusinessLayer.Controller.Controller.VerseMasterEntities.Verses where v.Translation.ToLower().StartsWith(translation.ToLower()) && v.BookId == bookId && v.ChapterNumber >= StartChapter && v.ChapterNumber <= EndChapter && (v.ChapterNumber == StartChapter ? (v.VerseNumber >= StartVerse) : true) && (v.ChapterNumber == EndChapter ? (v.VerseNumber <= EndVerse) : true) orderby v.ChapterNumber, v.VerseNumber ascending select v);
}
string traceString = ((System.Data.Objects.ObjectQuery)searchQuery).ToTraceString();
foreach (var entVerse in searchQuery)
{
VerseMaster.BusinessLayer.DataObjects.IVerse verse = new VerseMaster.BusinessLayer.DataObjects.Verse();
LoadVerseFromEntityVerse(ref verse, entVerse);
Console.Write(String.Format("Chapter={0} Verse={1} Text={2}\n", entVerse.ChapterNumber, entVerse.VerseNumber, entVerse.Verse));
//returnValue.Add((VerseMaster.BusinessLayer.DataObjects.Verse)verse);
}
}
return returnValue;
}
因此，出于某种原因，由于错误，我不得不将进入 linq 查询的每个参数转换为标准整数，不确定它是否相关。所以生成的sql是：

所以问题是，由于某种原因，它处理我给它的每个参数就好像我发送了 3 组相同的参数并连接起来，所以它返回相同的一组经文 3 次。我不确定为什么要这样做，因为我不是 linq 或实体框架的专家，有什么建议吗？
