推荐答案

在sql server中，您必须创建一个用于存储此表的表.

请参阅以下步骤

1)创建类似EmployeeLogin(id bigint，digitalsign varbinary(MAX))的表
2)隐瞒您的数字标牌，以便将表单上收到的数据输入到ByteArray中.
3)创建一个SP，以在上面创建的表上插入/更新信息.
4)在保存按钮上将此SP与参数(id和digitalsign)一起调用.

我有一些问题
1)您在winform上获得的用于数字签名的内容.
2)您使用哪个控件在表单上显示此数字签名.
3)您可以从该控件的代码中看到数据吗?

In sql server you have to create one table for storing this .

See the below steps

1) create table like EmployeeLogin (id bigint , digitalsign varbinary(MAX))
2) covert your digital sign which ever data received on form into ByteArray.
3) Create one SP to insert / update information on above created table.
4) call this SP along with parameter (id and digitalsign ) on save button.

I have some questions
1) What you have received on winform for digital sign.
2) which control you are using to display this digital sign on form.
3) are you able to see the data from code of that control ?
