Solution 1

Try like this..

C#

string connstring = "server=xyz\\sqlexpress;Database=myapp;Integrated Security=True";
            SqlConnection con = new SqlConnection(connstring);            
                con.Open();             

            SqlCommand sqlCmd = new SqlCommand(@"INSERT INTO Table_Name(Name) VALUES ('" + textBoxname.Text +  "')");
            sqlCmd.Connection = con;
         
            sqlCmd.ExecuteNonQuery();
            con.Close();

0) Your query is incorrect, you didn't close that properly(missing closing parenthesis at end)

C#

SqlCommand sqlCmd = new SqlCommand(@"INSERT INTO Table_Name(Name) VALUES (@name)",con);

1) You forgot to execute, below line is missing.

C#

sqlCmd.ExecuteNonQuery();

2) Don't use hard-code connectionstrings. Get those details from config files. Check the below one for sample
How to get Connection String from App.Config in C#[^]
3) Don't use Reserved keywords for columns. Use meaningful column names like Emp_Name(instead of Name)
Check it out for more details. Reserved Keywords[^]
4) Learn more before use things.
