C＃如何在Excel特定行中保存文本框信息？

Question

我在程序debug文件夹中放置了一个Excel文档，例如C＃project / bin / debug。

我有2个文本框和保存按钮的WinForm。 例如，用户必须在textbox1中输入他的名字，在texbox2中输入他的姓氏，然后单击保存将其保存。

我的问题是，当用户单击“保存”时，如何使textbox1输入保存在excel中的A2行中以及textbox2输入保存在B2行中？

excel文档应该不可见，并且应该在用户点击保存后自动保存文档。

谁能帮我？ 代码示例或指南链接将非常有用。

您可以使用OleDb对象处理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();
            }
        }
    }
}
