我无法从c#app保存数据到我的sql数据库没有错误

Question

我无法从c#app将数据保存到我的sql数据库,甚至没有给我任何错误.我错过了什么.它是一个简单的脚本,它将从Textbox中获取用户输入,并将复选框插入SQL数据库.这是我的剧本.

Initial catalog连接字符串中缺少.你应该在那里提到你的数据库名称.

@"Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Users\Asus\Documents\Visual Studio 2010\Projects\Kaizen Tracking System V1\Kaizen Tracking System V1\Database1.mdf;Initial Catalog=MyDatabase; Integrated Security=True;User Instance=True"
