C＃如何在Excel特定行中保存文本框信息？

Question

我在程序debug文件夾中放置了一個Excel文檔，例如C＃project / bin / debug。

我有2個文本框和保存按鈕的WinForm。 例如，用戶必須在textbox1中輸入他的名字，在texbox2中輸入他的姓氏，然后單擊保存將其保存。

我的問題是，當用戶單擊“保存”時，如何使textbox1輸入保存在excel中的A2行中以及textbox2輸入保存在B2行中？

excel文檔應該不可見，並且應該在用戶點擊保存后自動保存文檔。

誰能幫我？ 代碼示例或指南鏈接將非常有用。

您可以使用OleDb對象處理Excel文件。

using System;
using System.Data;
using System.Data.OleDb;

public static class Program
{
    ///This is a very basic example of how to use OleDb objects to edit spreadsheets.
    /// For more advanced operations, look into using OleDb with DataSets/DataTables.
    public static void Main(string[] args)
    {
        string Filename = "C:\\test.xls";
        //If you are using xls format, use this connection string.
        string ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Filename + ";Extended Properties=\"Excel 8.0;HDR=NO;\"";
        //If you are using xlsx format, use this connection string.
        //string ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + Filename + ";Extended Properties=\"Excel 12.0 Xml;HDR=NO\"";

        string Name_Value = "First Name";
        string Surname_Value = "Surname";

        string SQL1 = "UPDATE [Sheet1$A2:A2] SET F1='" + Name_Value + "'";
        string SQL2 = "UPDATE [Sheet1$B2:B2] SET F1='" + Surname_Value + "'";

        using(OleDbConnection Connection = new OleDbConnection(ConnectionString))
        {
            Connection.Open();
            using(OleDbCommand cmd1 = new OleDbCommand(SQL1,Connection))
            {
                cmd1.ExecuteNonQuery();
            }
            using(OleDbCommand cmd2 = new OleDbCommand(SQL2,Connection))
            {
                cmd2.ExecuteNonQuery();
            }
        }
    }
}
