如何将以逗号分割的字符串删除一个字符

[liushiying]

有两个变量
aa="123,364,478,364,890,432"
bb="364"
如何将aa改成"123,478,364,890,432"

[why2002plus]

Dim SearchWithinThis As String = "123,364,478,364,890,432"
Dim SearchForThis As String = "364"
Dim FirstCharacter As Integer = SearchWithinThis.IndexOf(SearchForThis)
Dim result = SearchWithinThis.Remove(FirstCharacter, SearchForThis.Length)
试试

[kssys]

直接:aa=aa.Replace("364,","")
if aa.LastIndexOf(",364")<>-1 再把最后面的那个",364"删掉即可。

这么晚了，发现各位都是夜猫子

length+1,哈，还有个逗号。

vb风格的，呵呵~~~~~

Dim aa As String = "123,364,478,364,890,432"
Dim bb As String = "364"
Dim iPos As Integer

iPos = aa.IndexOf("," & bb)
aa = aa.Substring(0, iPos) & aa.Substring(iPos + bb.Length + 1)
MsgBox(aa)

晕，是“删除一个字符”吗？

[daisi]

删除一个字符串还差不多

[iegrhn]

小心你的，和,

[alanzhou]

aa = "," & aa & ","
bb = "," & bb & ","

aa = aa.Replace(bb,",")

aa = aa.Substring(1,aa.length-1) //就是去掉头尾的两个","

[sz_lgp]

dim xx as string()
xx=aa.spilt()///aa="123,364,478,364,890,432"
dim m as integer
dim yy as string
bb="364"

for m=0 to xx.GetUpperBound(0)
if xx(m)=bb then
xx(m)=""
exit for
endif
endfor

for m=0 to xx.GetUpperBound(0)
if xx(m)<> "" then yy+=xx(m)& ","
endfor

楼主的真实意图,可能是取键字符串.
任给一字串,比如"A,BV,D,A,C,F,D",得到结果"A,BV,D,C,F";
没必要是得到这样的结果吧"BV,A,C,F,D"
