Question

我有正常工作代码：

public sealed partial class MainPage : Page
{

    public MainPage()
    {
        this.InitializeComponent();

        string name = tbxName.Text;
        string age = tbxAge.Text;
        string dinner = tbxDinner.Text;
    }



    private void OutputNewValues()
    {
        string answer = "Hello, " + tbxName.Text + " you are " + tbxAge.Text + " years old. " + tbxDinner.Text + " sounds yummy for dinner!";
        finalOutput.Text = answer;
    }
}

现在，在这一部分：

private void OutputNewValues()
    {
        string answer = "Hello, " + tbxName.Text + " you are " + tbxAge.Text + " years old. " + tbxDinner.Text + " sounds yummy for dinner!";
        finalOutput.Text = answer;
    }

我想使用我之前声明的字符串（名称，年龄，晚餐）而不是“tbxName.Text”。但它会给我一个错误，因为它在当前的上下文中不存在。

我该怎么做/我在哪里放置字符串部分以便在任何地方使用它？

好的，你走了。

将文本框值作为参数传递给参数。

public sealed partial class MainPage : Page
{
    public MainPage()
    {
        this.InitializeComponent();
        txtName.Text = "Your name";
        tbxAge.Text = "Your age";
        tbxDinner.Text = "Your dinner";
        OutputNewValues(txtName.Text, tbxAge.Text, tbxDinner.Text);
    }

    private void OutputNewValues(string name, string age, string dinner)
    {
        string answer = "Hello, " + name + " you are " + age + " years old. " + dinner + " sounds yummy for dinner!";
        finalOutput.Text = answer;
    }
}

或使用成员变量：

public sealed partial class MainPage : Page
{
    private string name = "Your name";
    private string age = "Your age";
    private string dinner = "Your dinner";
    public MainPage()
    {
        this.InitializeComponent();
        OutputNewValues();
    }

    private void OutputNewValues()
    {
        string answer = "Hello, " + name + " you are " + age + " years old. " + dinner + " sounds yummy for dinner!";
        finalOutput.Text = answer;
    }
}

在C＃中的不同方法中使用非文字字符串
