我有了〜10列，1-20行的Excel文件。我需要插入1-20行，各种数据元素。

I have an excel file that has ~10 columns and 1-20 rows. I need to insert 1-20 rows with various data elements.

我在想，如果有一种方法，我可以把一些标签在Excel文件中，以便他们能够被发现和更换。东西标志着一个列作为名称。这样，在code我只能说：

I was wondering if there was a way I could put some tags in the excel file so they could be found and replaced. Something that marks a column as "Name". That way in code I could just say:

名称[0] = object.name;

我不知道这确切的方法是可行的，但我真的不需要任何繁重和c的单元格位置的Excel文件我宁愿不硬$ C $可能会随时间而改变。

I'm not sure if this exact method is possible, but I really don't need any heavy lifting and I rather not hard code the cell locations as the excel file might change over time.

我还必须添加行一个隐藏的ID细胞。我想我能走过这座桥后来虽然。

I will also have to add a hidden 'ID' cell in row. I imagine I can cross that bridge later though.

推荐答案

使用ADO.NET易行添加到一个Excel工作表

Using ADO.NET is easy to add a row to an Excel Sheet

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();
}

在code以上假设你有一个第一行与列1列名的头......。 此外，code使用ACE OLEDB提供Excel中，而不是Microsoft.Jet.OleDb.4.0 2007年或2010年。

The code above assumes that you have a first row with an header with Column1... as column names. Also, the code use the ACE OleDB provider for Excel 2007 or 2010 instead of Microsoft.Jet.OleDb.4.0.

编辑：要引用一个命名范围，你可以更改SQL命令，这一个

To refer to a Named Range you could change the sql command to this one

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

唉，我无法找到一个方法来引用单个列。

Alas, I can't find a way to refer to the individual columns.
