C# ArrayList 查询如何解决在数组中查找字段并输出该字段

protected void btnBC_Click(object sender, EventArgs e) { DaXueShen p = new DaXueShen(txtXH .Text /*,txtXM .Text */,txtXB .Text ,txtJG .Text); //获取信息 p.sName = txtXM.Text; //获取姓名 p.setInfo(int.Parse (txtRXCJ .Text )); //获取成绩 list.Add(p ); //放入数组 } protected void btnCX_Click(object sender, EventArgs e) { string CX = txtCX.Text; foreach (DaXueShen p in list) //判断姓名查询 { if (list.Contains(CX )) { lbXS.Text = p.GetInfo(); //找到就输出该信息 } else { lbXS.Text = "查无此人！"; } } }

Answer 1

bool has=false;foreach (DaXueShen p in list) //判断姓名查询 { if (p.sName==CX ) { lbXS.Text = p.GetInfo(); //找到就输出该信息 has=true; break; } } if(!has) lbXS.Text = "查无此人！";
