您可以使用streamreader類來做到這一點。請使用它

FileStream stream = File.Open(filePath, FileMode.Open, FileAccess.Read); 

//1. Reading from a binary Excel file ('97-2003 format; *.xls) 
IExcelDataReader excelReader = ExcelReaderFactory.CreateBinaryReader(stream); 
//... 
//2. Reading from a OpenXml Excel file (2007 format; *.xlsx) 
IExcelDataReader excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream); 
//... 
//3. DataSet - The result of each spreadsheet will be created in the result.Tables 
DataSet result = excelReader.AsDataSet(); 
//... 
//4. DataSet - Create column names from first row 
excelReader.IsFirstRowAsColumnNames = true; 
DataSet result = excelReader.AsDataSet(); 

//5. Data Reader methods 
while (excelReader.Read()) 
{ 
    //excelReader.GetInt32(0); 
} 

//6. Free resources (IExcelDataReader is IDisposable) 
excelReader.Close();
