C# 如何比较C中两个列表框的项目名称？

我试着比较两个列表框的加工和非加工项目数和项目名称

我想在listMachedItems中显示加工项目名称，在LblMachedItemCount中显示加工项目计数

并在列表NOTMACHEDITEMS中显示未加工项目名称，在LBLNOTMACHEDITEMSCONT中显示未加工项目计数

请删除代码中不必要的空行好吗？请删除代码中不必要的空行好吗？我看不到项目Source，Intersect，Exception。我使用System.Windows.Forms；我看不到ItemsSource、Intersect，除了。我使用System.Windows.Forms；'System.Windows.Forms.ListBox'不包含'ItemsSource'的定义，并且找不到接受'System.Windows.Forms.ListBox'类型的第一个参数的扩展方法'ItemsSource'。是否缺少using指令或程序集引用？'System.Windows.Forms.ListBox'不包含'ItemsSource'的定义，并且没有可以找到接受类型为“System.Windows.Forms.ListBox”的第一个参数的扩展方法“ItemsSource”。是否缺少using指令或程序集引用？
