我试图将一个int值存储到表中,但如果我将表数据类型从int32更改为字符串,则我将获得此消息http://postimg.org/image/cv1cc4jkf/full/,则我将不断获得消息"不能隐式地将字符串转换为int"有人能帮我解决这个问题吗?easyScoreLabel, mediumScoreLabel和highScoreLabel是我从工具箱中拖到web应用程序上的标签。
protected void myScoresButton_Click(object sender, EventArgs e)
{
using (projectDBEntities1 dbcontext = new projectDBEntities1())
{
message aMessage = new message();
aMessage.userName = nameTextBox.Text;
aMessage.highScoreEasy = Int32.Parse(easyScoreLabel.Text);
aMessage.highScoreMedium = Int32.Parse(mediumScoreLabel.Text);
aMessage.highScoreHard = Int32.Parse(hardScoreLabel.Text);
dbcontext.messages.Add(aMessage);
dbcontext.SaveChanges();
}
GridView1.DataBind();
}
easyScoreLabel。Text是字符串。您需要将其转换为整型。
aMessage.highScoreEasy = Int.Parse(easyScoreLabel.Text);
aMessage.highScoreMedium = Int.Parse(mediumScoreLabel.Text);
aMessage.highScoreHard = Int.Parse(hardScoreLabel.Text);
