Question

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!");
    }
}

says it does not contain definition for it but on my GetSchedule .cs file i have it defined

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 "";
}

Check that the GetSchedule class is in the same namespace that you are trying to call it from, or that it is referenced.

It looks from your updated post like your function GetDataFromNumber is in a class called IDNumber – is this the problem?

Try:

IDnumber myNumber = new IDnumber();
myNumber.GetDataFromNumber(text);
