我有一个 Windows 窗体应用程序，其中用户将他们的姓名（名字和姓氏）输入到组合框中。我有一个添加按钮，可以将他们输入的任何值添加到组合框中并在下面列出。我想要做的是获取组合框中列出的名称并将它们输入到 Excel 中的单独行中。我在 excel 文件中也有 2 列“名字”和“姓氏”，因此组合框中的名称需要拆分。

这是我的excel代码：

if (!File.Exists(@"C:\gradsheet.xlsx"))
        {
            File.WriteAllBytes(@"C:\gradesheet.xlsx", Properties.Resources.gradesheet);
        }

        // if there is no title selected
        if (String.IsNullOrEmpty(cboSelect.Text))
        {
            MessageBox.Show("Please make sure a category is selected.", "No Subject Found Error", MessageBoxButtons.OK, MessageBoxIcon.Error);

            return;
        }


        object oOpt = System.Reflection.Missing.Value;

        Excel.Application excelApp = new Excel.ApplicationClass();
        Excel.Workbook wBook;


        string myPath = @"C:\gradesheet.xlsx";

        wBook = excelApp.Workbooks.Open(myPath, Missing.Value, Missing.Value,

          Missing.Value, Missing.Value,

          Missing.Value, Missing.Value,

          Missing.Value, Missing.Value,

          Missing.Value, Missing.Value,

          Missing.Value, Missing.Value,

          Missing.Value, Missing.Value);

        Excel.Worksheet wSheet = (Excel.Worksheet)wBook.Worksheets[1];

        wBook.Worksheets.get_Item(1);//get worksheet number
        wSheet.Name = cboSelect.Text;//define name



        //put name in excel(THIS IS WHERE I NEED THE COMBOBOX ITEMS IN EXCEL)
        excelApp.Cells[8, 1] = firstName;
        excelApp.Cells[8, 2] = lastName;


        //Subject Name to cell
        excelApp.Cells[5, 1] = cboSelect.Text;

        //these are some cleanup calls that I found in another example..
        excelApp.AlertBeforeOverwriting = false;
        excelApp.DisplayAlerts = false;
        excelApp.Save();
        excelApp.Quit();

        System.Runtime.InteropServices.Marshal.ReleaseComObject(excelApp);


        GC.Collect();

        GC.WaitForPendingFinalizers();



        DialogResult result;
        result = MessageBox.Show("Would you like to open the gradesheet?", "gradesheet", MessageBoxButtons.YesNo);
        if (result == DialogResult.Yes)
        {
            string gradesheet = @"C:\gradesheet.xlsx";
            Process.Start(gradesheet);
        }


    }

这是我将名字和姓氏分开的代码，但我不确定如何为组合框中的每个项目执行此操作：

string fullName = cboStudent.Text;
        string firstName;
        string lastName;
        string[] parts = fullName.Split(new string[] { ", " },        StringSplitOptions.None);
        if (parts.Length == 1)
        {
            parts = fullName.Split(' ');
            if (parts.Length == 1)
            {
                lastName = fullName;
                firstName = "";
            }
            else
            {
                lastName = parts[1];
                firstName = parts[0];
            }
        }
        else
        {
            lastName = parts[0];
            firstName = parts[1];
        }

好的，我在这里解决了代码，感谢您的帮助！

//Student Names
        for (int x = 0; x < cboStudent.Items.Count; x++)
            {
                string fullName = cboStudent.Items[x] as string;
                string firstName;
                string lastName;
                string[] parts = fullName.Split(new string[] { ", " }, StringSplitOptions.None);
                if (parts.Length == 1)
                {
                    parts = fullName.Split(' ');
                    if (parts.Length == 1)
                    {
                        lastName = fullName;
                        firstName = "";
                    }
                    else
                    {
                        lastName = parts[1];
                        firstName = parts[0];
                    }
                }
                else
                {
                    lastName = parts[0];
                    firstName = parts[1];
                }
                excelApp.Cells[8 + x, 1] = firstName;
                excelApp.Cells[8 + x, 2] = lastName;
            }

听起来在您的情况下，您希望组合框中的每个项目都使用组合框上的“项目”属性...

foreach (object name in cboStudent.Items)
{
      ...
}

如果您只想要从项目列表中选择的项目，您可以使用“SelectedItem”属性。

或者...

由于您可能希望将每个项目添加到工作簿中的不同单元格，您可以使用 for 循环，因此您也可以将整数用于单元格......

for (int x = 0; x < comboBox1.Items.Count; x++)
{
    object name = comboBox1.Items[x];

    // Split name here

    excelApp.Cells[8+x, 1] = firstName; 
    excelApp.Cells[8+x, 2] = lastName; 

}
