猜測哪些用戶將在文本框

Question

輸入有沒有在C＃的方式來猜測用戶將要輸入？例如，當您在Visual Studio中輸入內容並從Fi開始時，File就會作爲答案並提示用戶按Enter鍵輸入。有沒有辦法做到這一點與文本框？

這實際上取決於您的應用程序的複雜性，但直接的方法是將文本框上的AutoCompleteMode屬性設置爲相關AutoCompleteMode枚舉。來自MSDN鏈接的示例代碼

private void Form1_Load(object sender, EventArgs e) 
{ 
    // Create the list to use as the custom source. 
    var source = new AutoCompleteStringCollection(); 
    source.AddRange(new string[] 
        { 
         "January", 
         "February", 
         "March", 
         "April", 
         "May", 
         "June", 
         "July", 
         "August", 
         "September", 
         "October", 
         "November", 
         "December" 
        }); 

    // Create and initialize the text box. 
    var textBox = new TextBox 
        { 
         AutoCompleteCustomSource = source, 
         AutoCompleteMode = 
          AutoCompleteMode.SuggestAppend, 
         AutoCompleteSource = 
          AutoCompleteSource.CustomSource, 
         Location = new Point(20, 20), 
         Width = ClientRectangle.Width - 40, 
         Visible = true 
        }; 

    // Add the text box to the form. 
    Controls.Add(textBox); 
}
