Question

我复制了一个旧表单，并使用不同的字段创建了这个新表单，现在收到以下错误消息。

\ www \ assets \ root \ forms \ revenueanalysis.aspx.cs（50,13）：错误CS0103：当前上下文中不存在名称“EmailCollections”

\ www \ assets \ root \ forms \ revenueanalysis.aspx.cs（61,18）：错误CS0103：当前上下文中不存在名称“Utility”

\ www \ assets \ root \ forms \ revenueanalysis.aspx.cs（74,18）：错误CS0103：当前上下文中不存在名称“Utility”

Answer 1

您正试图在btnSubmit_Click方法的末尾访问“EmailCollections”对象：

EmailCollections.SendNewrevenueanalysisFormEmail(name, emailAddress, emailAddress2, phone, title, company, comment, specialties,  cases,  this);

您还尝试在多个位置访问“Utility”对象：

if (!Utility.IsEmailValid(tbEmail.Text))

您收到的错误是因为系统不知道在哪里找到这些对象。是否有可能当您复制旧的for时，您丢失了顶部指向缺少对象的命名空间的一些“using”语句？如果你仍然有旧的副本，我建议检查“使用”语句，并包括那些包含缺少的对象定义的语句。
