c# - Raw SQL を使用してデータベースのフィールドを更新するには?

Question

where条件をチェックインするときにsenderIdに基づいてIsIgnoredフィールドを更新する必要があります.ループから比較したsenderIdを識別しません.あいまいな列名「senderid」のような例外をスローします.この問題を解決するには、これについて教えてください.

  foreach (var senderId in senderIdList)
                    {
                        using (var context = new BSoftWEDIIContext())
                        {
                           var ediDocuments = context.EDIDocuments.SqlQuery("Update EDIDocument SET IsIgnored=1 from EDIDocument edi  inner JOIN  FileDetails files on edi.FileDetailsId = files.Id where edi.IsDeleted = 0 and  edi.SenderID =senderId and edi.DocumentTypeID != 3 and edi.DocumentTypeID != 5 and edi.DocumentTypeID != 2 and edi.IsIgnored = 0 and files.IsDeleted = 0" );

                        }

このように試しました：

 var ediDocuments = context.EDIDocuments.SqlQuery("Update EDIDocument SET IsIgnored=1 from EDIDocument edi  inner JOIN  FileDetails files on edi.FileDetailsId = files.Id where edi.IsDeleted = 0 and  edi.SenderID ='149825353' and edi.DocumentTypeID != 3 and edi.DocumentTypeID != 5 and edi.DocumentTypeID != 2 and edi.IsIgnored = 0 and files.IsDeleted = 0", new SqlParameter
                            {
                                ParameterName = "senderId",
                                DbType = System.Data.DbType.String,
                                Value = senderId
                            });


  foreach (var senderId in senderIdList)
                    {

                        using (var context = new BSoftWEDIIContext())
                        {
                            var ediDocuments = context.EDIDocuments.SqlQuery("Update EDIDocument SET IsIgnored=1 from EDIDocument edi  inner JOIN  FileDetails files on edi.FileDetailsId = files.Id where edi.IsDeleted = 0 and  edi.SenderID=@senderId and edi.DocumentTypeID != 3 and edi.DocumentTypeID != 5 and edi.DocumentTypeID != 2 and edi.IsIgnored = 0 and files.IsDeleted = 0", new SqlParameter("@senderId", senderId));
