表单控件是与Excel早期版本兼容的原始控件，通过表单控件，用户可以快速地将数据填写到模板文档中，如果你想在不使用VBA代码的情况下轻松引用单元格数据并与其进行交互，也可以使用表单控件。本文将介绍如何使用C\#和[Free Spire.XLS组件][Free Spire.XLS]给Excel表格添加常见的表单控件例如文本框、单选按钮、复选框和组合框，以及如何删除现有的表单控件。

**插入表单控件**

//创建Workbook实例
    Workbook workbook = new Workbook();
    //添加工作表
    Worksheet sheet = workbook.Worksheets[0];
    
    //插入文本框
    sheet.Range["A2"].Text = "姓名：";
    ITextBoxShape textBox = sheet.TextBoxes.AddTextBox(2, 2, 18, 65);
    textBox.Text = "肖恩";
    textBox.Fill.ForeColor = Color.GreenYellow;
    textBox.HAlignment = CommentHAlignType.Center;
    textBox.VAlignment = CommentVAlignType.Center;
    
    //插入单选按钮
    sheet.Range["A4"].Text = "性别：";
    IRadioButton radioButton = sheet.RadioButtons.Add(4, 2, 18, 65);
    radioButton.CheckState = CheckState.Checked;
    radioButton.Text = "男";
    
    radioButton = sheet.RadioButtons.Add(4, 4, 18, 65);
    radioButton.Text = "女";
    
    //插入复选框
    sheet.Range["A6"].Text = "爱好：";
    ICheckBox checkBox = sheet.CheckBoxes.AddCheckBox(6, 2, 18, 65);
    checkBox.CheckState = CheckState.Checked;
    checkBox.Text = "摄影";
    
    checkBox = sheet.CheckBoxes.AddCheckBox(6, 4, 18, 65);
    checkBox.Text = "唱歌";
    
    
    checkBox = sheet.CheckBoxes.AddCheckBox(6, 6, 18, 65);
    checkBox.CheckState = CheckState.Checked;
    checkBox.Text = "旅行";
    
    //插入组合框           
    sheet["A8"].Text = "职业：";
    sheet["A9"].Text = "学生";
    sheet["A10"].Text = "教师";
    sheet["A11"].Text = "医生";
    
    IComboBoxShape comboBox = sheet.ComboBoxes.AddComboBox(8, 2, 18, 65);
    comboBox.ListFillRange = sheet["A9:A11"];           
    comboBox.LinkedCell = sheet.Range["C8"];
    comboBox.SelectedIndex = 2;
    
    //保存文档
    workbook.SaveToFile("AddFormControls.xlsx", ExcelVersion.Version2010);

**删除表单控件**

//创建Workbook实例
    Workbook workbook = new Workbook();
    //载入Excel文档
    workbook.LoadFromFile("AddFormControls.xlsx");
    
    //获取第一个工作表
    Worksheet sheet = workbook.Worksheets[0];
    
    //删除工作表中所有的复选框
    for (int i = 0; i < sheet.CheckBoxes.Count; i++)
    {
        sheet.CheckBoxes[i].Remove();
    }
    
    //保存文档
    workbook.SaveToFile("RemoveCheckBoxes.xlsx", ExcelVersion.Version2010);
