点击一个button按钮，增加一行，含有dropdownList、TextBox控件，急急急！！请给出代码！！

Answer 1

在button的click里写这几句

TextBox textBox1 = new TextBox() ;
textBox1.Location = new System.Drawing.Point(84, 237);
textBox1.Name = "textBox1";
textBox1.Size = new System.Drawing.Size(100, 21);
textBox1.TabIndex = 3;

DropdownList dropdownList1 = new DropdownList ();
dropdownList1.FormattingEnabled = true;
dropdownList1.Location = new System.Drawing.Point(64, 105);
dropdownList1.Name = "dropdownList1";
dropdownList1.Size = new System.Drawing.Size(120, 88);
dropdownList1.TabIndex = 2;

this.Controls.Add(dropdownList1);
this.Controls.Add(textBox1);
