Question

Is there any solution to overcome case-sensitive problem for contains method.

I have code like below

string str = m_name;
return avobj.Viewname.Contains(str);

Eg: Welcome Here
welcome here

Both are same names but case is different. If I give ‘W’ in search box it is returning only 1st one. but I need both names display.

I am storing the names in collection. And resultant values ( searched values ) are storing in List.

You can use String.IndexOf(string, StringComparison). If it returns anything other than -1, then the substring was present. You can then specify an appropriately case-insensitive comparison.
