使用ClosedXML将数据从excel导出到数据库表

Question

我必须从只有一列的excel文件读取数据行，然后我必须将数据库中的行保存到表中。 在我的项目中，我必须使用ClosedXML .dll。 我有搜索，但我找不到示例。 你能帮我吗？ 感谢

对于ClosedXML部分，你可以参考的文档在https://github.com/ClosedXML/ClosedXML/wiki/Finding-and-extracting-the-data

private static void Main() 
{ 
    List<String> categories; 
    List<String> companies; 
    ExtractCategoriesCompanies("NorthwindData.xlsx", out categories, out companies); 

    // Do something with the categories and companies 
} 

private static void ExtractCategoriesCompanies(string northwinddataXlsx, out List<string> categories, out List<string> companies) 
{ 
    categories = new List<string>(); 
    const int coCategoryId = 1; 
    const int coCategoryName = 2; 

    var wb = new XLWorkbook(northwinddataXlsx); 
    var ws = wb.Worksheet("Data"); 

    // Look for the first row used 
    var firstRowUsed = ws.FirstRowUsed(); 

    // Narrow down the row so that it only includes the used part 
    var categoryRow = firstRowUsed.RowUsed(); 

    // Move to the next row (it now has the titles) 
    categoryRow = categoryRow.RowBelow(); 

    // Get all categories 
    while (!categoryRow.Cell(coCategoryId).IsEmpty()) 
    { 
    String categoryName = categoryRow.Cell(coCategoryName).GetString(); 
    categories.Add(categoryName); 

    categoryRow = categoryRow.RowBelow(); 
    } 

    // There are many ways to get the company table. 
    // Here we're using a straightforward method. 
    // Another way would be to find the first row in the company table 
    // by looping while row.IsEmpty() 

    // First possible address of the company table: 
    var firstPossibleAddress = ws.Row(categoryRow.RowNumber()).FirstCell().Address; 
    // Last possible address of the company table: 
    var lastPossibleAddress = ws.LastCellUsed().Address; 

    // Get a range with the remainder of the worksheet data (the range used) 
    var companyRange = ws.Range(firstPossibleAddress, lastPossibleAddress).RangeUsed(); 

    // Treat the range as a table (to be able to use the column names) 
    var companyTable = companyRange.AsTable(); 

    // Get the list of company names 
    companies = companyTable.DataRange.Rows() 
    .Select(companyRow => companyRow.Field("Company Name").GetString()) 
    .ToList(); 
}
