将简单数据从.Net插入Excel文件的最简单方法

Question

我有一个excel文件,有~10列和1-20行.我需要插入1-20行与各种数据元素.

我想知道是否有办法在excel文件中放置一些标签,以便找到并替换它们.将列标记为"名称"的东西.在代码中这样我可以说:

Name[0] = object.name;

我不确定这种确切的方法是否可行,但我真的不需要任何繁重的工作,我宁愿不对单元格位置进行硬编码,因为excel文件可能会随着时间的推移而改变.

我还必须在行中添加隐藏的"ID"单元格.我想我以后可以越过那座桥了.

使用ADO.NET很容易向Excel工作表添加行

string fileName = @"D:\test.xlsx"; 
string connectionString = String.Format(@"Provider=Microsoft.ACE.OLEDB.12.0;" + 
        "Data Source={0};Extended Properties='Excel 12.0;HDR=YES;IMEX=0'", fileName); 

using(OleDbConnection cn = new OleDbConnection(connectionString))
{
    cn.Open();
    OleDbCommand cmd1 = new OleDbCommand("INSERT INTO [Sheet1$] " + 
         "([Column1],[Column2],[Column3],[Column4]) " + 
         "VALUES(@value1, @value2, @value3, @value4)", cn);
   cmd1.Parameters.AddWithValue("@value1", "Key1");
   cmd1.Parameters.AddWithValue("@value2", "Sample1");
   cmd1.Parameters.AddWithValue("@value3", 1);
   cmd1.Parameters.AddWithValue("@value4", 9);
   cmd1.ExecuteNonQuery();
}

上面的代码假定您有一个第一行,其头部包含Column1 ...作为列名.此外,代码使用Excel OleDB提供程序用于Excel 2007或2010而不是Microsoft.Jet.OleDb.4.0.

编辑:要引用命名范围,您可以将sql命令更改为此命令

    OleDbCommand cmd1 = new OleDbCommand("INSERT INTO [yourNamedRange] " + 
                        "VALUES(@value1, @value2, @value3, @value4)", cn);

唉,我找不到引用单个列的方法.

    private Excel.Application app = null;
    private Excel.Workbook workbook = null;
    private Excel.Worksheet worksheet = null;
    private Excel.Range workSheet_range = null;
    private const int FIRTSCOLUMN= 0 //Here const you will use to select good column
    private const int FIRSTROW= 0
    private const int FIRSTSHEET= 1

    app = new Excel.Application();
    app.Visible = true;
    workbook = app.Workbooks.Add(1);
    worksheet = (Excel.Worksheet)workbook.Sheets[FIRSTSHEET];
    addData(FIRSTROW,FIRTSCOLUMN,"yourdata");


 public void addData(int row, int col, string data)
    {
        worksheet.Cells[row, col] = data;

    }
