如何从字符串中删除结尾逗号
问题描述：
public string display()
{
string st="";
DataTable dt= (DataTable)ViewState["CurrentData"];
for (int i = 0; i < dt.Rows.Count ; i++)
{
st += dt.Rows[i]["item"].ToString() + ",";
}
return st;
}
这是我的函数，它以字符串格式存储值
例如:-abc @ gmail.com，xya @ yahoo.com，dfd @ gmail.com，
如何从字符串中删除最后一个逗号
例如:-abc @ gmail.com，xya @ yahoo.com，dfd @ gmail.com

st = st.Remove(st.Length-1，1);
st = st.Remove(st.Length - 1, 1);
st = st.Substring(0，st.Length- 1);
st=st.Substring(0,st.Length-1);
