    private void btnSubmit_Click_1(object sender, EventArgs e)
    {

    }
}
}

提交按钮不起作用。当我在字段中输入信息后单击提交时，它什么也不做。我不确定在 private void btnSubmit_Click_1 之后放入。我正在使用 VB 2010 及其 Windows 窗体项目。

您已将两种方法链接到您的按钮。

private void btnSubmit_Click_1(object sender, EventArgs e)

和

private void btnSubmit_Click(object sender, EventArgs e)

将您的代码放入btnSubmit_Click_1.

或者

您可以调整附加到单击事件的方法，方法是在设计视图中选择按钮的属性，然后单击黄色闪电，找到click事件并更改方法名称。

this.btnSubmit.Click += new System.EventHandler(this.btnSubmit_Click_1);

您在该方法中的代码：

private void btnSubmit_Click_1(object sender, EventArgs e)
{

}

你期待它到底做什么？

我想你想要：

this.btnSubmit.Click += new System.EventHandler(this.btnSubmit_Click);

您的代码还有很多其他问题，其中一个是真正 的“必须抓住所有”异常处理btnSubmit_click。

您必须单击处理程序方法：btnSubmit_Click和btnSubmit_Click_1.

OnlybtnSubmit_Click_1被注册来处理点击，它的body是空的。您可以删除该方法并将注册更改为：

this.btnSubmit.Click += btnSubmit_Click;
