將數據從數據庫加載到richtextBox

Question

using (SqlConnection myDatabaseConnection = new SqlConnection(myConnectionString.ConnectionString)) 
      { 
       myDatabaseConnection.Open(); 
       using (SqlCommand mySqlCommand = new SqlCommand("Select [EmpID], [Name], [Address], [Birthday] from EmpTable where EmpID = @EmpID", myDatabaseConnection)) 
       SqlCommand.Parameters.AddWithValue("@EmpID", textBox1.Text); 
       { 
       using (SqlDataReader sqlreader = mySqlCommand.ExecuteReader()) 
       { 

        if (sqlreader.Read()) 
        { 
         textBox2.Text = sqlreader.GetInt32(sqlreader.GetOrdinal("EmpID")).ToString();       
         textBox3.Text = sqlreader.GetString(sqlreader.GetOrdinal("Name")); 
         textBox4.Text = sqlreader.GetString(sqlreader.GetOrdinal("Address")); 
         textBox5.Text = sqlreader.GetString(sqlreader.GetOrdinal("Birthday")); 
        } 
       } 
       } 
      }

如何我可以從數據庫中的數據加載到richBox？是這樣的：

我在哪裏可以突出顯示數據和複製的文本。

使用String.Format，就像這樣：

String template = 
@"EmpID\t\t{0} 
Name\t\t{1} 
Address\t\t{2} 
Birthday\t\t{3}"; 

    using (SqlConnection c = new SqlConnection(config.ConnectionString)) 
    { 
     c.Open(); 
     using (SqlCommand cmd = new SqlCommand("Select [EmpID], [Name], [Address], [Birthday] from EmpTable where EmpID = @EmpID", c)) 
     { 
      cmd.Parameters.AddWithValue("@EmpID", textBox1.Text); 
      using (SqlDataReader rdr = mySqlCommand.ExecuteReader()) 
      { 
       if (rdr.Read()) 
       { 
        Int32 empId = rdr.GetInt32(rdr.GetOrdinal("EmpID")).ToString();       
        String name = sqlreader.GetString(sqlreader.GetOrdinal("Name")); 
        String addr = sqlreader.GetString(sqlreader.GetOrdinal("Address")); 
        String bday = sqlreader.GetString(sqlreader.GetOrdinal("Birthday")); 

        textbox.Text = String.Format(template, empId, name, addr, bday); 
       }//if 
      }//using 
     }//using
