通过vb.net发布数据到SQL表格使用onClick Submit按钮的形式

-2

我是VB.net的新手，我正在开发Visual Studio 2015中的项目。在我的应用程序的选项卡之一中，我尝试通过表单发布将新记录插入到SQL表中，但是一旦我点击按钮，什么都不会发生，并且不会添加新记录。我目前的代码如下，任何帮助将是伟大的！感谢：通过vb.net发布数据到SQL表格使用onClick Submit按钮的形式

您的命令文本被抬起。例如，需要引用字符串。尝试在SSMS中运行该语句。如果它不能从那里工作，它不会从.Net工作。

此外，你在做什么是一个安全问题。使用存储过程并将值作为参数传递。建立一个在.Net中执行的声明将导致更糟的性能和注入漏洞。
