如何检查值是否在C#的comboBox中?
问题描述：
我的组合框具有男性"& 如果用户未选择，则为女性，仅键入任何内容，错误提示必须输入"invalid input！".类似的内容
我的代码但是很烂，我不知道怎么了
if(comboBox.text！="male" || comboBox.text！="female")
{
messagebox.show("invalid！");
}
my combobox has the "male" & "female if the user did not select just type anything an error must prompt "invalid input!"something like that
my code but it sucks do not works i dont know whats wrong
if(comboBox.text !="male" ||comboBox.text !="female")
{
messagebox.show("invalid!");
}
答
try:
try:
if (comboBox.SelectedIndex == -1) {
messagebox.show("invalid!");
}
祝你好运！
Good luck!
