public void button2_Click(object sender, System.EventArgs e)
{
string text = textBox1.Text;
Mainform = this;
this.Hide();
GetSchedule myScheduleFinder = new GetSchedule();
string result = myScheduleFinder.GetDataFromNumber(text);// says there is no definition
if (!string.IsNullOrEmpty(result))
{
MessageBox.Show(result);
}
else
{
MessageBox.Show("Enter A Valid ID Number!");
}
}
说它不包含它的定义,但在我的GetSchedule .cs文件中我定义了它
public string GetDataFromNumber(string ID)//defined here
{
foreach (IDnumber IDCandidateMatch in IDnumbers)
{
if (IDCandidateMatch.ID == ID)
{
StringBuilder myData = new StringBuilder();
myData.AppendLine(IDCandidateMatch.Name);
myData.AppendLine(": ");
myData.AppendLine(IDCandidateMatch.ID);
myData.AppendLine(IDCandidateMatch.year);
myData.AppendLine(IDCandidateMatch.class1);
myData.AppendLine(IDCandidateMatch.class2);
myData.AppendLine(IDCandidateMatch.class3);
myData.AppendLine(IDCandidateMatch.class4);
//return myData;
return myData.ToString();
}
}
return "";
}

您确定GetDataFromNumber
是否在class
定义中,而不是在结束括号之后?
答案 1 :(得分:0)
检查GetSchedule类是否与您尝试从中调用它的名称空间相同,或者引用它。
从你的更新帖子中看起来像你的函数GetDataFromNumber在一个名为IDNumber的类中 - 这是问题吗?
尝试:
IDnumber myNumber = new IDnumber();
myNumber.GetDataFromNumber(text);

问题是因为您正在创建Web表单并将代码从一个页面复制到另一个页面。执行此操作时,必须小心并确保不更改页面中的第一个指令。它告诉Web代码页面后面应该找到什么,它应该找到定义和代码逻辑。您遇到此问题的原因是当您从一个页面复制并粘贴到另一个页面时,它带来了另一个页面的指令,很可能您没有在页面定义中调用的函数。因此,请确保更改了网页中的第一行,以指向其继承的正确.cs
文件和类。
