var issNoIP = SplitIssueNoF(txtIssueNo.Text);
issueNoIp stores issueNoIP="value1" and issueNoIP="value2"
now i want to store this value alone issueNoIP into string
string split = Convert.ToString(issNoIP);
if i do so,this is my following error
Error 6 Cannot apply indexing with  to an expression of type 'object'
