private void button2_Click(object sender, EventArgs e)
    {

        radioButton1.text = Month[i];
        radioButton2.text = Month[i];
        radioButton3.text= Month[i];

        i = (i + 1) % 5;

    }

出现 3 个错误，说“'System.Windows.Form.RadioButton' 不包含'text' 的定义，并且找不到接受第一个参数类型'System.Windows.Forms.RadioButton' 的扩展方法'text'（是您缺少 using 指令或程序集引用）

我对此很陌生，并试图自学 C#，所以请耐心等待我，在此先感谢。

Adding to Rodrigo's answer:

private void button2_Click(object sender, EventArgs e) {

    radioButton1.Text = Month[i];
    radioButton2.Text = Month[i];
    radioButton3.Text= Month[i];

    i = (i + 1) % 5;

}

Here you are trying to set the Text property (string) to and integer (Month).

Try:

private void button2_Click(object sender, EventArgs e) {

    radioButton1.Text = Month[i].ToString();
    radioButton2.Text = Month[i].ToString();
    radioButton3.Text= Month[i].ToString();

    i = (i + 1) % 5;

}

Also, each of those RadioButtons will have the same text (Month number). Not sure if that is intended.

Additionally, you should use if else or a switch statement instead of if blocks in this case when checking for the current month. Currently, if Month == 1, it will still be checked against 2, 3, 4, etc needlessly.

Finally, consider limiting the creation of random numbers to a specified range.

C# 区分大小写。您要查找的属性是文本，而不是文本。

private void button2_Click(object sender, EventArgs e) {

    radioButton1.Text = Month[i];
    radioButton2.Text = Month[i];
    radioButton3.Text= Month[i];

    i = (i + 1) % 5;

}
