在C#僵尸框架SDK3中,要更改Prompt.Choice选项的颜色,可以使用ConsoleColor枚举来实现。下面是一个示例代码:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Bot.Builder.Dialogs;
using Microsoft.Bot.Builder.Dialogs.Choices;
using Microsoft.Bot.Schema;
namespace ZombieFrameworkSDK3
{
public class ZombieDialog : ComponentDialog
{
public ZombieDialog(string dialogId) : base(dialogId)
{
}
protected override async Task<DialogTurnResult> OnBeginDialogAsync(DialogContext innerDc, object options, CancellationToken cancellationToken = default(CancellationToken))
{
var choices = new List<Choice>
{
new Choice { Value = "Option 1" },
new Choice { Value = "Option 2" },
new Choice { Value = "Option 3" }
};
var promptOptions = new PromptOptions
{
Prompt = MessageFactory.Text("Please select an option:"),
Choices = choices,
Style = ListStyle.Auto
};
return await innerDc.PromptAsync(nameof(ChoicePrompt), promptOptions, cancellationToken);
}
protected override async Task<DialogTurnResult> OnContinueDialogAsync(DialogContext innerDc, CancellationToken cancellationToken = default(CancellationToken))
{
var result = (FoundChoice)innerDc.Result;
// Handle the selected choice here
return await innerDc.EndDialogAsync();
}
}
}
在上述代码中,我们使用了ChoicePrompt来创建一个选择提示框。通过设置PromptOptions的Style属性为ListStyle.Auto,可以根据终端的支持情况自动选择合适的样式。
如果你想更改选项的颜色,可以使用Console.ForegroundColor属性来设置控制台的前景色。下面是一个示例代码:
protected override async Task<DialogTurnResult> OnBeginDialogAsync(DialogContext innerDc, object options, CancellationToken cancellationToken = default(CancellationToken))
{
var choices = new List<Choice>
{
new Choice { Value = "Option 1", Synonyms = new List<string> { "1" } },
new Choice { Value = "Option 2", Synonyms = new List<string> { "2" } },
new Choice { Value = "Option 3", Synonyms = new List<string> { "3" } }
};
var promptOptions = new PromptOptions
{
Prompt = MessageFactory.Text("Please select an option:"),
Choices = choices,
Style = ListStyle.Auto
};
// Set the console foreground color to yellow
Console.ForegroundColor = ConsoleColor.Yellow;
var result = await innerDc.PromptAsync(nameof(ChoicePrompt), promptOptions, cancellationToken);
// Reset the console foreground color
Console.ResetColor();
return result;
}
在上述代码中,我们在选择提示框显示之前将控制台的前景色设置为黄色(ConsoleColor.Yellow),然后在选择完成后将前景色重置为默认值(Console.ResetColor())。
这样就可以更改Prompt.Choice选项的颜色了。请注意,这种方式只会影响控制台输出的颜色,不会改变实际的选项颜色。如果你想要更改实际选项的颜色,可以考虑使用其他UI库或自定义控件来实现。
