C# 动态文本框和标签的验证
好吧，我完全不知道该怎么做。我需要做的是验证一些文本框的正则表达式和所有文本框的必填字段。我对它进行了设置，这样当用户点击按钮时，每次都会显示一组新的输入字段，这样，如果他们有一个以上的工作经验，他们就可以无限地输入。我试过的代码不起作用。还可能需要注意的是，由于遇到这个问题，我到目前为止只做了一个地址。一旦我明白了这一点，剩下的我就可以做了 ASP.net代码只是一个按钮。 C#代码：C# 动态文本框和标签的验证,c#,asp.net,validation,dynamic,C#,Asp.net,Validation,Dynamic,好吧，我完全不知道该怎么做。我需要做的是验证一些文本框的正则表达式和所有文本框的必填字段。我对它进行了设置，这样当用户点击按钮时，每次都会显示一组新的输入字段，这样，如果他们有一个以上的工作经验，他们就可以无限地输入。我试过的代码不起作用。还可能需要注意的是，由于遇到这个问题，我到目前为止只做了一个地址。一旦我明白了这一点，剩下的我就可以做了 ASP.net代码只是一个按钮。 C#代码： protected void Page_Load(object sender, EventArgs e) {
