Question

我试图通过在Form2中的文本框中输入值来搜索位于dataGridView1，Form1上的值.DataGridView1设置为从.xls文件加载数据。

我知道Form1和Form2中缺少一些代码来执行此任务，这是因为我不熟悉Visual Studio和C＃代码。

非常感谢你的帮助:)）

这是位于Form1中的代码：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Data.OleDb;

namespace Plan_de_lucru
{
    public partial class frPlanDeLucru : Form
    {
        public frPlanDeLucru()
        {
            InitializeComponent();
        }

        private void TextBox1_TextChanged(object sender, EventArgs e)
        {

        }

        private void ctrlLoad_Click(object sender, EventArgs e)
        {

            string constr = "Provider = MicroSoft.Jet.OLEDB.4.0; Data Source=" + TextBox1.Text + "; Extended Properties =\"Excel 8.0; HDR=Yes;\";";
            OleDbConnection con = new OleDbConnection(constr);
            OleDbDataAdapter sda = new OleDbDataAdapter("Select * From [" + textBox2.Text + "$]", con);
            DataTable dt = new DataTable();
            sda.Fill(dt);
            dataGridView1.DataSource = dt;
            new Form2().Show();
            this.Show();
        }

        private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
        {


            }
        }


    }

这是位于Form2中的代码：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace Plan_de_lucru
{
    public partial class Form2 : Form
    {
        public Form2()
        {
            InitializeComponent();
        }

        private void search_button_Click(object sender, EventArgs e)
        {
            String str = "select * from searchBox where ( Name like '%' + @search + '%')";
            BindingSource bs = new BindingSource();
            bs.DataSource = dataGridView1.DataSource;
            bs.Parameters.Add("@search",)



        }
    }
}
