编译器错误消息：BC30452：运算符''&' '没有为类型定义
''String''和''System.Web.UI.WebControls.TextBox''。
Can somebody tell me why I get this message with the following code?
Compiler Error Message: BC30452: Operator ''&'' is not defined for types
''String'' and ''System.Web.UI.WebControls.TextBox''.
通常这意味着你试图使用< asp：TextBox>
的内容而不指定其.Text属性
例如位置而不是Location.Text
然而，我想知道是否可能是因为你忘记了双b / b
这里的引用：
Normally that means you''re trying to use the contents of an <asp:TextBox>
without specifying its .Text property
e.g. Location instead of Location.Text
However, I''m wondering if it might be because you''ve forgotten the double
quotes here:
"< body>" &安培; vbCrLf& vbCrLf& _
发生事故的地点：
Location.Text& _
"<body>" & vbCrLf & vbCrLf & _
Location where accident occurred:
Location.Text & _

您不需要在HTML正文中设置html / head / body标签
....并且，在VbCrLf线程中，我们确定你不能在HTML中使用VbCrLf。
其他：你必须*将所有HTML内容放在一行。
你不能用代码打破界限。
摆脱所有的VbCrLf以及所有&并将所有HTML写在一行中，
使用< br>"< br />"来打破正文的内容。或< P ...< / P>根据需要。
另外，你不能在你的HTML中插入文本框控件。
所以，Check1.Text也出来了。
如果你想引用他们的内容，用户填写后，
将其捕获到变量并使用它，然后写入正文。
插入：
Dim Check1 as String = Check1.Text
Dim Check2 as String = Check2。文字
昏暗的位置为String = Location.Text
之前Dim objMM as New MailMessage（）
和在编写正文时，请使用：
mail.Body =" Hi，< p>事故发生的地点是： &安培;位置& "<峰; br />" &安培; Check1& "。"
''等
你*可以*使用&引用文本变量。
注意引号的位置。

============================ =======
" dancer" < da **** @ microsoft.com在消息新闻中写道：uU ************* @ TK2MSFTNGP05.phx.gbl ...
You don''t need to set the html/head/body tags within the HTML body
....and, in the VbCrLf thread, we established that you can''t use VbCrLf in HTML.
Something else : you *must* put all the HTML content in ONE line.
You can''t break the lines with code.
Get rid of all the "VbCrLf" and all the "&" and write all your HTML in a single line,
line-breaking the body''s content with "<br />" or "<P... </P>" as needed.
Also, you can''t insert Textbox controls into your HTML.
So, Check1.Text is out, too.
If you want to reference their content, after a user fills them out,
capture it to a variable and use that, before writing to the body.
insert :
Dim Check1 as String = Check1.Text
Dim Check2 as String = Check2.Text
Dim Location as String = Location.Text
before "Dim objMM as New MailMessage()"
and, when composing the body, use :
mail.Body="Hi, <p>The location where the accident occurred is :" & Location & "<br/>" & Check1 & "."
'' etc.
You *can* use the & to reference text variables.
Notice the location of the quote marks.
