Question

我的程序存在问题。我试图能够使用键入文本框的所有信息并将它们存储到txt文件。我有一个地址类来格式化信息和表格。

我在这里有地址类：

public class Addresses
{
    private string name { get; set; }
    private string address { get; set; }
    private string city { get; set; }
    private string state { get; set; }
    private string zipCode { get; set; }
    private string phoneNum { get; set; }

    public Addresses()
    {
    }

    public Addresses(string fName, string ad, string cty, string st, string  zip, string pNum)
    {
        name = fName;
        address = ad;
        city = cty;
        state = st;
        zipCode = zip;
        phoneNum = pNum;
    }
    public override string ToString()
    {
        return "Name: " + name +
            "\nAddress: " + address +
            "\nCity: " + city +
            " State: " + state +
            " Zip Code: " + zipCode +
            "\nPhone#: " + phoneNum;
            ;
    }

}

}

            }
        }


        private void textBox1_TextChanged(object sender, EventArgs e)
        {




        }

        private void textBox3_TextChanged(object sender, EventArgs e)

        }

        private void label7_Click(object sender, EventArgs e)
        {

        }
    }
    }

请有人告诉我我做错了什么。文件get已保存，但保存的文件中没有任何内容。

Answer 1

btnSave_Click中有以下相反的内容：

Addresses User = new Addresses();
textBox1.Text = User.name;
textBox3.Text = User.address;
textBox5.Text = User.city;
textBox6.Text = User.state;
textBox7.Text = User.zipCode;
textBox8.Text = User.phoneNum;
User.ToString();

在上述情况下，您将文本框设置为用户的值。当您调用ToString时，这些值将是未定义的，因为它们从未在默认构造函数中设置。

相反，你可能想要做相反的事情，即根据文本框设置用户的值，然后获取用户的信息。

编辑：您的地址类具有私有变量，因此您无法通过Form类直接设置用户信息。但是，您可以使用其他构造函数，然后在btnSave_Click函数中调用ToString。

Addresses User = new Addresses(textBox1.Text, textBox3.Text, textBox5.Text, textBox6.Text, textBox7.Text, textbox8.Text);
txtInfo.Text = User.ToString();

用户信息到txt要读取的文件
