Search with LINQ with case sensitive in C# winform

Shefali Lahariya

i am using code:

Activeuser.DataSource = temp.Where(x=>x.displayName.Contains(txtsearch.Text)).ToList();

var temp1 = objAvailableActiveUsersListResponse.users.Where(x => x.displayName.Contains(txtsearch.Text)).ToList();

int lstcount = temp1.Count;

Activeuser.DataSource = null;

if (lstcount > 0)

{

object[] row = new object[3];

// dataGridView1.Rows.Add(row);

for (int i = 0; i < lstcount; i++)

{

string DisplayName = temp1[i].displayName;

string uid = temp1[i].uid.ToString();

row = new object[] { DisplayName, false, uid };

Activeuser.Rows.Add(row);

}

but its search but in case of case sensitiv. its not working properly

An alternative option is to use String.Equals overload method which takes StringComparison as parameter
Activeuser.DataSource = temp.Where(x => String.Equals(x.displayName,txtsearch.Text,StringComparison.InvariantCultureIgnoreCase)).ToList();
var temp1 = objAvailableActiveUsersListResponse.users.Where(x => String.Equals(x.displayName,txtsearch.Text,StringComparison.InvariantCultureIgnoreCase)).ToList();
