Question

我遇到了Linq查询的问题，我试图在SQL中将其用作IN。在Linq中想一想Contains。我会发布我的代码，也许有人可以帮助我？

var claimsearch =
    (from x in dbContext.view_ImageVerification_Shortened
    where x.intCurrentImageVerificationStatusID.Contains.(2,3,4,5).
    select new
    {
        intImageVerificationID = x.intImageVerificationID,
        intClaimID = x.intClaimID,
        intCurrentCaseStatusLookUpID = x.intCurrentCaseStatusLookUpID,
        vcharCurrentCaseStatusName = x.vcharCurrentCaseStatusName,
        vcharEnergyEmployeeFullName = x.vcharEnergyEmployeeFullName,
        vcharClaimDocsTabHTTPNOCTSLink = x.vcharClaimDocsTabHTTPNOCTSLink,
        intDocumentID = x.intDocumentID,
        vcharDocumentName = x.vcharDocumentName,
        intDocumentTypeID = x.intDocumentTypeID,
        vcharDocumentType = x.vcharDocumentType,
        vcharDocumentFullFileName = x.vcharDocumentFullFileName,
        vcharDocumentHttpFullFileName = x.vcharDocumentHttpFullFileName,
        intContainerID = x.intContainerID,
        vcharContainerDescription = x.vcharContainerDescription,
        intContainerTypeID = x.intContainerTypeID,
        intCurrentImageVerificationTrackingID = x.intCurrentImageVerificationTrackingID,
        intCurrentImageVerificationStatusID = x.intCurrentImageVerificationStatusID,
        vcharCurrentImageVerificationStatusDescription = x.vcharCurrentImageVerificationStatusDescription,
        intCurrentImageVerificationTrackingUserID = x.intCurrentImageVerificationTrackingUserID,
        dtmCurrentImageVerificationTrackingDate = x.dtmCurrentImageVerificationTrackingDate,
        vcharCurrentImageVerificationTrackingNotes = x.vcharCurrentImageVerificationTrackingNotes,
        vcharCurrentImageVerificationStatusDescriptionUserAndDate = x.vcharCurrentImageVerificationStatusDescriptionUserAndDate,
        intPageCount = x.intPageCount,
        intClaimType = x.intClaimType
    }).ToList();

你的病情应该是：

where new[] {(int?) 2,3,4,5}.Contains(x.intCurrentImageVerificationStatusID)
// cast to int? for nullable

如果阵列中存在intCurrentImageVerificationStatusID，则返回true。

您可以将数字提取到数组中，然后在查询中使用它，例如：

nt?[] array = new int?[] {2, 3, 4, 5 };

然后在条件中执行：

where array.Contains(x.intCurrentImageVerificationStatusID)

Linq使用IN的条款
