这个节目应该从你输入的日期或每日漫画中获得加菲尔德漫画。第一个按钮应该允许你选择一个自定义漫画,但只有每日漫画(按钮2)似乎工作在这里代码:

using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace Garfield_Comic_Viewer
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
int month = int.Parse(textBox1.Text);
int day = int.Parse(textBox2.Text);
int year = int.Parse(textBox3.Text);
switch (month)
{
case 1:
month = 01;
break;
case 2:
month = 02;
break;
case 3:
month = 03;
break;
case 4:
month = 04;
break;
case 5:
month = 05;
break;
case 6:
month = 06;
break;
case 7:
month = 07;
break;
case 8:
month = 08;
break;
case 9:
month = 09;
break;
}
switch (day)
{
case 1:
day = 01;
break;
case 2:
day = 02;
break;
case 3:
day = 03;
break;
case 4:
day = 04;
break;
case 5:
day = 05;
break;
case 6:
day = 06;
break;
case 7:
day = 07;
break;
case 8:
day = 08;
break;
case 9:
day = 09;
break;
}
pictureBox1.ImageLocation = ("http://garfield.com/uploads/strips/" +year+ "-" +month+ "-" + day + ".jpg");
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void button2_Click(object sender, EventArgs e)
{
string mon = DateTime.Now.ToString("MM");
string d = DateTime.Now.ToString("dd");
string y = DateTime.Now.ToString("yyyy");
pictureBox1.ImageLocation = "http://garfield.com/uploads/strips/" + y + "-" + mon + "-" + d + ".jpg";
DateTime whole = DateTime.Now;
}
}
}
答案 0 :(得分:4)
问题是你期望整数表现得像字符串一样。
您缺少的一点是:
int a = 01;
与:
相同 int a = 1;
没有区别。你不能填充一个整数。您需要的是使用格式说明符将格式整数转换为字符串。像这样:
pictureBox1.ImageLocation =
string.Format("http://garfield.com/uploads/strips/{0:D4}-{1:D2}-{2:D2}.jpg",
year, month, day);
这将给出一个字符串,其中包含格式为yyyy-mm-dd的数字。
(填充字符串格式的整数的文档是here。)
