如何写入所选单元格旁边的 Excel 单元格？

Question

我的程序从 Excel 文档中读取数据（姓名）并将它们显示在 CheckListBox 上，供用户选择他们的姓名。然后用户必须从一系列 RadioButtons 中选择一种颜色。如何让程序在包含其姓名的单元格旁边的单元格中写入他们选择的颜色？

以下是我的程序的摘录：

public void ColorChoice()
    {
        ColorGreen.CheckedChanged += new EventHandler(radioButton_CheckedChanged);
        ColorYellow.CheckedChanged += new EventHandler(radioButton_CheckedChanged);
        ColorRed.CheckedChanged += new EventHandler(radioButton_CheckedChanged);
        ColorBlue.CheckedChanged += new EventHandler(radioButton_CheckedChanged);
    }

    void radioButton_CheckedChanged(object sender, EventArgs e)
    {
        RadioButton Color = sender as RadioButton;

        if (Color == null)
        {
            MessageBox.Show("No Color Selected");
            return;
        }

        // Ensure that the RadioButton.Checked property
        // changed to true.
        if (Color.Checked)
        {
            // Keep track of the selected RadioButton by saving a reference
            // to it
            string SelectedColor = Color.Text;

            //This is where it will write the color to the Excel File
            Excel.Application ExcelApp = new Excel.Application();
            Excel.Workbook ExcelBook = ExcelApp.Workbooks.Open(@"C:\\Users\\Blayne\\Desktop\\Prototype3\\Prototype1\\Prototype1\\Save Folder\\Students.xlsx", 0, false, 5, "", "", true, Excel.XlPlatform.xlWindows, "\t", true, false, 1, 0);
            Excel._Worksheet ExcelSheet = (Excel._Worksheet)ExcelBook.Sheets[1];


        }


    }

    public void ImportStudentDetails()
    {
        Excel.Application ExcelApp = new Excel.Application();
        Excel.Workbook ExcelBook = ExcelApp.Workbooks.Open(@"C:\\Users\\Blayne\\Desktop\\Prototype3\\Prototype1\\Prototype1\\Save Folder\\Students.xlsx", 0, false, 5, "", "", true, Excel.XlPlatform.xlWindows, "\t", true, false, 1, 0);
        Excel._Worksheet ExcelSheet = (Excel._Worksheet)ExcelBook.Sheets[1];

        NameListBox.CheckOnClick = true;
        NameListBox.Name = "NameListBox";
        NameListBox.TabIndex = 1;
        NameListBox.SelectionMode = SelectionMode.One;
        NameListBox.ThreeDCheckBoxes = true;
        NameListBox.DisplayMember = "Name";
        NameListBox.Items.Add(ExcelSheet.Cells[2, 1].text);
        NameListBox.Items.Add(ExcelSheet.Cells[3, 1].text);
        NameListBox.Items.Add(ExcelSheet.Cells[4, 1].text);
        NameListBox.Items.Add(ExcelSheet.Cells[5, 1].text);
        NameListBox.Items.Add(ExcelSheet.Cells[6, 1].text);
        NameListBox.Items.Add(ExcelSheet.Cells[7, 1].text);
        NameListBox.Items.Add(ExcelSheet.Cells[8, 1].text);
        NameListBox.Items.Add(ExcelSheet.Cells[9, 1].text);
        NameListBox.Items.Add(ExcelSheet.Cells[10, 1].text);
        NameListBox.Items.Add(ExcelSheet.Cells[11, 1].text);
        Controls.Add(NameListBox);

    }



    public class SaveName
    {
        public static void SaveNameData(object obj, string filename)

        {

            XmlSerializer sr = new XmlSerializer(obj.GetType());
            TextWriter writer = new StreamWriter(filename);
            sr.Serialize(writer, obj);
            writer.Close();
        }
    }

    public class Data
    {
        private string name1;

        public string Name1
        {
            get { return name1; }
            set { name1 = value; }
        }
    }



    private void StartButton_Click(object sender, EventArgs e)
    {
        var SNames = new List<string>();
        foreach (var c in NameListBox.CheckedItems)
        {
            SNames.Add(c.ToString());
        }

        string SName = string.Join(",", SNames.ToArray());
        try
        {
            Data info = new Data();
            info.Name1 = SName;
            Login.SaveName.SaveNameData(info, "Name.xml");
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }

        this.Hide();
        Form2 f2 = new Form2();
        f2.Closed += (s, args) => this.Close();
        f2.Show();

    }

    public static void SaveStudentData(object data, string directory)
    {
        using (TextWriter writer = new StreamWriter(directory, true))
        {
            XmlSerializer sr = new XmlSerializer(data.GetType());
            sr.Serialize(writer, data);
            writer.Close();
        }

    }

忽略我的程序将选择的名称写入 xml 文件，因为它可以将名称传输到另一个表单。 提前致谢。
