将控件直接添加到工作表时，我不断收到异常。代码放置在表单内，而不是功能区的一部分。

这是我的代码：

// using TExcel = Microsoft.Office.Tools.Excel;
// MyGlobalsWrapper references the Globals object, which has been passed across an
// AppDomain barrier

Excel.Worksheet activeWorksheet = MyGlobalsWrapper.Application.ActiveSheet;
TExcel.Worksheet toolsSheet = MyGlobalsWrapper.Factory.GetVstoObject(activeWorksheet);
var range = activeWorksheet.Range["A1:F20"];

var button = new System.Windows.Forms.Button();
button.Text = "HELLO!";
button.Visible = true;

// Both of these fail with the same exception

// Add manually (as the Range object might be the problem
toolsSheet.Controls.AddControl(button,10,10,button.Width,button.Height,id);

// Add using a range (which is more ideal for my usage)
toolsSheet.Controls.AddControl(button,range ,id);

例外情况如下：

System.Runtime.Serialization.SerializationException occurred

我曾尝试将其包装在 中System.Windows.Forms.UserControl，但我有同样的问题。

注意：我想使用 Windows 控件，因为我打算在工作表中嵌入一个用户控件，而不仅仅是一个按钮。我从一个简单的控制开始，然后开始工作。所以我需要一个使用 Windows 窗体控件（最好是 UserControl）而不是 Excel 框架提供的任何控件的解决方案。

您是否在单独的 AppDomain 中运行此代码？

如果您是，那么 ControlsCollection 将需要跨 AppDomain 屏障进行编组。与大多数编组一样，这将通过序列化来实现。

是否可以在主 Excel AppDomain 中运行此代码？
