C# String 折行(換行)、連接符號

資料來源: https://dotblogs.com.tw/yypass2002/2013/08/13/114391

1. 使用 + 符號 – 連接符號

string strSQL= "SELECT * FROM HumanResources.Employee AS e"
    + " INNER JOIN Person.Contact AS c"
    + " ON e.ContactID = c.ContactID"
    + " ORDER BY c.LastName"; 

                 
2.使用 @ 符號 – 連接符號

string strSQL= @"SELECT * FROM HumanResources.Employee AS e
     INNER JOIN Person.Contact AS c
     ON e.ContactID = c.ContactID
     ORDER BY c.LastName";  

 
3.Label 控制項中要換行”<br>”

lblUser.Text = "編號：" + lblSno.Text + "<br>"
                        + "姓名：" + txtName + "<br>"
                        + "電話：" + txtTel ;

 
4.TextBox控制項中要換行”\r\n”

textBox1.Text = "編號:" + id + "\r\n"
                         + "姓名" + Name +"\r\n"
                         + "電話" + Tel;

 
注意其 TextMode需設為MultiLine 才會有效果；預設為SingleLine
或於程式碼中先加入
txtBox1.TextMode =TextBoxMode .MultiLine ;
