请让我们考虑下表
这是使用c#窗口形式完成的,也让我们考虑来自我的sql的以下图片
以及
问题是,当我们向form1添加一些数据时,它没有保存在数据库中,有基于此表单创建的c#代码,我的问题是我应该添加的内容,以便它也可以在sql中更新表数据库?这是sql代码

}
private void tableBindingNavigatorSaveItem_Click(object sender, EventArgs e)
{
this.Validate();
this.tableBindingSource.EndEdit();
this.tableAdapterManager.UpdateAll(this.tatoDataSet1);
}
private void Form1_Load(object sender, EventArgs e)
{
// TODO: This line of code loads data into the 'tatoDataSet1.Table' table. You can move, or remove it, as needed.
this.tableTableAdapter.Fill(this.tatoDataSet1.Table);
}
private void tableDataGridView_CellContentClick(object sender, DataGridViewCellEventArgs e)

进一步看,在提交更改之前,需要使用输入表单中指定的值将新行添加到表中。我添加了指导你的伪代码。我无法提供确切的代码,因为我不知道所有输入字段或数据库列的名称。我假设button3_click是你的保存按钮。
然后,在将更新应用到适配器之前单击“保存”按钮时,尝试将更改提交到数据集:
private void button3_Click(object sender, EventArgs e)
{
//Create a new row for your table
dim row as DataRow
row = this.tatoDataSet1.tables(0).NewRow
' Add Values to Row here
' This is where you will set the values for each column in your rows to the input entered
' Something like:
dr.Column1 = txtInput1.text;
ds.tables(0).rows.add(row)
this.Validate();
this.tableBindingSource.EndEdit();
this.tatoDataSet1.AcceptChanges();
this.tableAdapterManager.UpdateAll(this.tatoDataSet1);
MessageBox.Show("information is saved");
}
