private void tbNbCat_KeyDown(object sender, KeyEventArgs e) { int id=0; if (e.KeyCode == Keys.Return){ id = int.Parse(tbNbCat.Text); MessageBox.Show(id.ToString()); createTxtTeamNames(id); } } public void createTxtTeamNames(int id) { TextBox[] txtTeamNames = new TextBox[id]; for (int u = 0; u < id; u++) { txtTeamNames[u] = new TextBox(); } int i = 0; foreach (TextBox txt in txtTeamNames) { string name = "TeamNumber" + i.ToString(); txt.Name = name; txt.Text = name; txt.Location = new Point(0, 32 + (i * 28)); txt.Visible = true; this.Controls.Add(txt); i++; } }是MySQL中的保留字。您可以更改列名称（更好的解决方案），也可以在反引号中更新查询包装Keys。
