问题描述
我有一点问题就是用一些，来连接一个字符串。这是我的代码：
Dim mystring as string =""
for i = 1到3
mystring = mystring& "，" &安培; Otherstring
next i
我正在得到这样的结果
" a，b，c，
和数字我得到这个结果
"，1,2,3"
我怎样才能做到a，b，c和1,2,3 ？
谢谢。

< blockquote>也许是这样的：
dim mystring as string =""
for i = 1 to 3
如果len（mystring）= 0那么
mystring = Cstr（i）
else
mystring = mystring& ， &安培; CStr（i）
结束如果
下一个我
这将给你1,2,3
希望这会有所帮助..

hi，
我有一个小问题，用一些，来连接一个字符串。这是我的代码：
Dim mystring as string =""
for i = 1 to 3
mystring = mystring& ; "，" &安培; Otherstring
接下来我就得到这样的结果
a，b，c，"
和得到这个结果的数字
"，1,2,3"
如何使它成为a，b，c和1,2,3 ？
谢谢。

这里是'单程。请注意，该功能不做任何检查或修剪，
所以它会愉快地附加空字符串或字符串，只包含
空格。另请注意，如果你要做很多这些字符串
连接，你应该使用StringBuilder。
函数AppendCommaDelimitedValue（ByVal s作为String，ByVal appendValue
As String）As String
如果s.Length = 0那么
s = appendValue
Else
s = s& "，" &安培; appendValue
结束如果
返回s
结束功能

mystring = mystring & "," & otherstring

and i m getting the result like this
"a,b,c,"
and with numbers i m getting this result
",1,2,3"
how can i make it "a,b,c" and "1,2,3" ?

maybe something like this:
dim mystring as string = ""
for i=1 to 3
if len(mystring) = 0 then
mystring = Cstr(i)
else
mystring = mystring & ", " & CStr(i)
end if
next i
this will give you 1,2,3
hope this helps..
Imran.

Here''s one way. Note that the function doesn''t do any checking or trimming,
so it will happily append empty strings or strings containing nothing but
white space. Also note that if you''re going to do very many of these string
concatenations, you should use a StringBuilder instead.
Function AppendCommaDelimitedValue(ByVal s As String, ByVal appendValue
As String) As String
If s.Length = 0 Then
s = appendValue
Else
s = s & "," & appendValue
End If
Return s
End Function
