数组长度的问题~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

问个问题啊
比如我传过来的字符串是1，2，；3，4，；
如果
string flagbagain= returnvalue.Substring(0,returnvalue.Length - 1);//除掉最后的那个分号
string [] infoarray = flagbagain.Split(';');
for (int i= 0; i < infoarray.Length; i++)
{
string [] infoarray1 = infoarray.Substring(0,infoarray.Length - 1); //为了除掉最后的那个逗号，这句会报错，不知道咋写
string [] detail = infoarray1.Split(',');
}

string [] infoarray = flagbagain.Split(new string[] { ";" }, StringSplitOptions.RemoveEmptyEntries);
for (int i= 0; i < infoarray.Length; i++)
{
string [] detail = infoarray1Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries);
}

这样就行了.

谢谢版主哦
string [] infoarray = flagbagain.Split(';');
for (int i= 0; i < infoarray.Length; i++)
{
string infoarray1 = infoarray[i].Substring(0,infoarray.Length - 1);
string [] detail = infoarray1.Split(',');
}
我这样也可以实现所以发上来，给大家参考

infoarray
是数组当然要infoarray[i]

3楼的方法当然可以,但是何必在多定义几个变量呢?
而且,如果最后没有一个逗号,你那种写法不就错了??呵

string [] infoarray1 = infoarray.Substring(0,infoarray.Length - 1);

这样肯定报错啊
后面返回的是字符串，可是却要赋值给数组
