Search with LINQ with case sensitive in C# winform

 

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
