C＃CsvHelper CsvHelper.Excel ClosedXML，給我的基本代碼的語法錯誤

-4

嘿我有一個CSVHelper的問題。C＃CsvHelper CsvHelper.Excel ClosedXML，給我的基本代碼的語法錯誤

我需要讀取一個相當不錯的Excel文件。但不幸的是，標題行不在第1行，它在第4行。我已經遇到了這個問題，並且始終以相同的方式處理它，在將它傳遞給CsvReader之前，在ExcelParser上調用.Read()。但是，今天的事情是不同的，當我運行這段代碼，ClosedXML讓我在reader.GetRecords<T>().ToList() 錯誤語法錯誤：

using CsvHelper.Excel; 
using CsvHelper; 

var excelParser = new ExcelParser(FilePath); 

int header = 2; 
for (int i = 0; i < header; i++) 
{ 
    excelParser.Read(); 
} 


using (var reader = new CsvReader(excelParser)) 
{ 
    reader.Configuration.Delimiter = ";"; 
    reader.Configuration.RegisterClassMap<MaterialTemplateClassMap>(); 
    var records = reader.GetRecords<TemplatesSheet>().ToList(); 
}

的類映射是很基本的Excel文件都不復雜。所以我沒有看到那裏的問題。也許我錯過了一些東西。在從ClosedXML，消息運行時：「語法錯誤」，ExceptionType：System.Exception的

語法錯誤？什麼是確切的錯誤信息？你在編譯或運行時得到這個嗎？請更完整地回答你的問題。 – DavidG

如果您收到異常，發佈其詳細信息和堆棧跟蹤以及重現問題的代碼通常是一個好主意。請閱讀[mcve] –

缺少異常類型和消息......另外，我在「Excel根本不復雜」中直接哼了一聲 –

確定。確切的問題是：從xlsx到csv的轉換無法正常工作。 CsvHelper.Excel不正確處理單元格中的公式。直到我嘗試將數據讀取爲可能在轉換過程中損壞的CSV文件時，它纔會拋出異常。修復：手動刪除所有公式或查找另一個xlsx到csv轉換器。
