串流讀取器中的反斜槓

我嘗試讀取數據遷移的csv文件。這是文件的外觀（它的UTF8格式）

"MIGRATIONID","ACCOUNTID","MIGRACCOUNTID","CONFIGID","MEDIUMID","PRIMCLASSID","SECCLASSID","SALESCODE","CONTENT","REGELNR","LIST_ATTRIBUTES","PACKAGE_TYPE","VERWIJSADVERTENTIE","NIET_PUBLICEREN" 
"ITM-0015-0163","62222532","ACT-0000-4755","61635591","TGP","TG_P_GV_01","","TG_Print_GV","%NAME%|%STREETNAME%|%HOUSENUMBER%|%HOUSENUMBEREXT%||%POSTALCODE%|%LOCALITY%|%AREACODE%|%CONNECTIONNUMBER%|%URL%|%EMAIL%||%COMMERCIAL%||||||%PRODNR%","10","","","","FALSE" 
"ITM-0015-0172","62222140","ACT-0000-4779","61636356","TGP","TG_P_GV_01","","TG_Print_GV","%NAME%|%STREETNAME%|%HOUSENUMBER%|%HOUSENUMBEREXT%||%POSTALCODE%|%LOCALITY%|%AREACODE%|%CONNECTIONNUMBER%|%URL%|%EMAIL%||%COMMERCIAL%||||||%PRODNR%","10","","","","FALSE"

正如你所看到的，它是用逗號分隔的。

我讀使用一個StreamReader它：

System.IO.StreamReader file = new System.IO.StreamReader(documentFilePath, Encoding.UTF8); 
while ((line = file.ReadLine()) != null) 
{ 
    //perform the transformation 
}

我有這個做了萬次沒有問題。但是，當行被讀取時，它們突然變成這樣（從調試手錶複製）：

"\"ITM-0015-0163\",\"62222532\",\"ACT-0000-4755\",\"61635591\",\"TGP\",\"TG_P_GV_01\",\"\",\"TG_Print_GV\",\"%NAME%|%STREETNAME%|%HOUSENUMBER%|%HOUSENUMBEREXT%||%POSTALCODE%|%LOCALITY%|%AREACODE%|%CONNECTIONNUMBER%|%URL%|%EMAIL%||%COMMERCIAL%||||||%PRODNR%\",\"10\",\"\",\"\",\"\",\"FALSE\""

所有這些反斜槓從哪裏來？我是否讀錯了文件。我怎樣才能防止這個？因爲它破壞了我對數據的進一步處理。
