This is really easy. Don't get confused and write int test = 1;, then MessageBox.Show("test:" + 1), because then if test's value changes, that will just print 1instead of test's new value 2.
这真的很容易。不要弄糊涂int test = 1;，然后写，MessageBox.Show("test:" + 1)因为如果test的值改变了，那只会打印1而不是test新的值2。
Example:
例子：
int test = 1;
test = test + 1;
MessageBox.Show(test);

Use string formatting with the message box:
对消息框使用字符串格式：
int courseId = 0;
DialogResult result = MessageBox.Show(string.Format("Print Course No {0} ?", courseId), "Print Confirmation", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
