你好，我很难在我的测验中转换到下一个问题c#转到测验的下一页,c#,arrays,visual-studio-2010,C#,Arrays,Visual Studio 2010,你好，我很难在我的测验中转换到下一个问题 private void Form1_Load(object sender, EventArgs e) { Random random = new Random(); int Month = random.Next(0); if (Month == 0) { radioButton1.Text = "January"; radi

罗德里戈的回答补充道：

radioButton1.Text = Month[i];
radioButton2.Text = Month[i];
radioButton3.Text= Month[i];
i = (i + 1) % 5;
}
文本属性（字符串）设置为和整数（月）
尝试：
此外，每个单选按钮都有相同的文本（月号）。不确定这是否是有意的
此外，在本例中，在检查当前月份时，应使用if else
或switch
语句，而不是if
块。当前，如果month==1
，则仍将不必要地对照2、3、4等进行检查
最后，考虑将随机数的生成限制为a＜/p>，加上罗德里戈的回答：
private void button2_Click(object sender, EventArgs e) {
radioButton1.Text = Month[i];
radioButton2.Text = Month[i];
radioButton3.Text= Month[i];
i = (i + 1) % 5;
}
这里您试图将文本属性（字符串）设置为和整数（月）

<>最后，考虑把随机数的创建限制到.< /p>，你能简化你的问题吗？似乎太长了，你能简化你的问题吗？似乎太长的欢呼了，但是它仍然没有改变页面。当我点击“Null ReavigyExcExchange是未处理的”按钮时，它出现了一个错误。对象引用未设置为对象的实例。“有什么想法吗？？？@callum-这是因为变量Month
超出范围。它是在另一个方法中定义的。将其定义为类的字段，而不是方法。欢呼声确实有帮助，但仍然没有更改页面。当我单击按钮时，出现了一个错误，显示”NullReferenceException未处理“对象引用未设置为对象的实例”。有什么想法吗？？？@callum-这是因为变量Month
