c# - C# 多个相同的表单，来自 SQL 数据库的不同值
问题描述
我因为一个我无法解决的问题而陷入困境。该项目正在使用 C# Winforms。列表中有多个作业，当用户选择一个作业时，会打开另一个表单。在此表单上，用户可以开始工作，也可以从他/她离开的地方继续工作。作业启动时，计时器启动，当用户单击暂停时，计时器停止并将其写入数据库（使用 MS SQL 更新语句，经过时间并将作业状态写入数据库）。当用户启动多个（比如说 2 个工作）工作时，可以看到 2 个具有不同值的相同表单。到目前为止一切都很好，但是当用户同时启动两个作业时，它会绑定值并且计时器计数 x2 次。换句话说，它们就像一个表格一样，并且计数器根据相同数量的表格进行多次计数。
有没有办法区分它们之间的多个相同形式？我希望你们能听懂我的英语，祝你们有美好的一天！！
