Question

两个问题：

您如何合并两位代码？将它们作为两个大块似乎有点多余！

您将如何通过多个列进行搜索（如果在以下任何列中找到结果，则返回结果：名称，性别，年龄）？

private void button1_Click(object sender, EventArgs e)
{
        BindingSource bs = new BindingSource();
        bs.DataSource = dataGridView1.DataSource;
        bs.Filter = "id like '%" + textBox1.Text + "%'";
        dataGridView1.DataSource = bs;
}

private void textBox1_TextChanged(object sender, EventArgs e)
{
        BindingSource bs = new BindingSource();
        bs.DataSource = dataGridView1.DataSource;
        bs.Filter = "id like '%" + textBox1.Text + "%'";
        dataGridView1.DataSource = bs;
}

Answer 1

回答您的第一个问题：

创建一个函数来获取您的搜索语句，并在需要时调用它。如下所示：

        private void button1_Click(object sender, EventArgs e)
        {
           SearchData();
        }

        private void textBox1_TextChanged(object sender, EventArgs e)
        {
             SearchData();
        }
        private void SearchData()
        {
            BindingSource bs = new BindingSource();
            bs.DataSource = dataGridView1.DataSource;
            bs.Filter = "id like '%" + textBox1.Text + "%'";
            dataGridView1.DataSource = bs;
         }

回答第二个问题：

您可以按如下方式编写过滤器：

bs.Filter = "id like '%" + textBox1.Text + "%' and name like '%" + textBox2.Text + "%'";
