Answer 1

先去msdn上把个进制 之间的转换关系 弄明白了，你也就会写了。

Answer 2

//十进制转二进制
Console.WriteLine(Convert.ToString(69, 2));
//十进制转八进制
Console.WriteLine(Convert.ToString(69, 8));
//十进制转十六进制
Console.WriteLine(Convert.ToString(69, 16));//二进制转十进制
Console.WriteLine(Convert.ToInt32(”100111101″, 2));
//八进制转十进制
Console.WriteLine(Convert.ToInt32(”76″, 8));
//十六进制转十进制
Console.WriteLine(Convert.ToInt32(”FF”, 16));

Answer 3

在控制台程序运行一下，搞明白了，移植到你winform里面就成了。

开发一个进制转换器示例
 private void btn_transform_Click(object sender, EventArgs e)
        {
            try
            {
                Action();//调用Action方法进行转换操作
            }
            catch (Exception ex)
            {
                MessageBox.Show(//如果出现异常则提示错误信息
                    ex.Message+" 请重新输入","出错！");
            }
        }//codego.net/tags/1/1/
        // 此方法用于进制转换
        private void Action()
        {
            if (cbox_select.SelectedIndex != 3)//判断用户输入是否为十六进制数
            {
                long P_lint_value;//定义长整型变量
                if (long.TryParse(txt_value.Text, out P_lint_value))//判断输入数值是否正确并赋值
                {
                    if (cbox_select.SelectedIndex == 0)//判断用户输入的是否为十进制数
                    {
                        switch (cbox_select2.SelectedIndex)
                        {
                            case 0:
                                txt_result.Text = txt_value.Text;//将十进制转为十进制

Answer 5

其实就是将字符串按combobox1的选择项转成数字,再按combobox2的选项转回字符串
这有什么不懂的吗

Answer 6

将某整数itoa在将某字符串atoi
