文本框没有任何值

Question

我试图在几秒钟内编写一个年龄计算器，但TextBox txtOutput没有获得任何值。没有编译错误，所以它必须是另一个错误，但我无法检测到它。

public partial class Form1 : Form
{
    public DateTime bDate;
    public Form1()
    {
        InitializeComponent();
    }
    private void btnBerechne_Click(object sender, EventArgs e)
    {   
        DateTime birthDate = dtpInput.Value;
        txtOutput.Text = GetAge(bDate);        
    }

    public string GetAge(DateTime bDate)
    {
        DateTime birthDate = dtpInput.Value;
        TimeSpan Calculator = DateTime.Now - birthDate;
        int x = (int) Calculator.TotalSeconds;
        return x.ToString();
    }
}
}

任何帮助都会受到赞赏。感谢

适用于此：

public partial class Form1 : Form
{
    public DateTime bDate;
    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        lblSeconds.Text = GetAge(Convert.ToDateTime(dtpInput.Text));
    }

    public string GetAge(DateTime bDate)
    {
        DateTime birthDate = bDate;
        TimeSpan Calculator = DateTime.Now - birthDate;
        int x = (int)Calculator.TotalSeconds;
        return x.ToString();
    }
}
