Answer 1

有两种主要方法可以在组合框上自动完成。第一种方法是将源代码设置为 comboBox.Items：&nbsp; &nbsp; &nbsp; &nbsp; comboBox1.AutoCompleteMode = AutoCompleteMode.Suggest;&nbsp; &nbsp; &nbsp; &nbsp; comboBox1.AutoCompleteSource = AutoCompleteSource.ListItems;&nbsp; &nbsp; &nbsp; &nbsp; comboBox1.Items.AddRange(new []{"Omg", "So Kewel"," I love it"});&nbsp;第二种是设置自定义源。在第二种情况下，下拉箭头不会显示任何内容，但自动完成功能会在您开始键入时显示。&nbsp; &nbsp; &nbsp; &nbsp; comboBox1.AutoCompleteMode = AutoCompleteMode.Suggest;&nbsp; &nbsp; &nbsp; &nbsp; comboBox1.AutoCompleteSource = AutoCompleteSource.CustomSource;&nbsp; &nbsp; &nbsp; &nbsp; var list = new List<string>() {"Omg", "So Kewl", "I love it"};&nbsp; &nbsp; &nbsp; &nbsp; var collection = new AutoCompleteStringCollection();&nbsp; &nbsp; &nbsp; &nbsp; collection.AddRange(list.ToArray());&nbsp; &nbsp; &nbsp; &nbsp; comboBox1.AutoCompleteCustomSource = collection;
