C# 在.NET中的字符串之间放置换行符

我使用以下c代码通过我的应用程序发送电子邮件#

但我收到的邮件是“SheerazahmedShehzorehydrabadsheerashadrabadsindhpakistan03453594552034598750258741”表格_1@hotmail.comsingle“即合并所有值，我希望textboxt的每个值都在一个单独的新行中，即

Sheeraz Ahmed
Shehzore
Hyderabad 

等等

或者更好地使用stringbuilder或string.Format

StringBuilder bodyBuilder = new StringBuilder("");
bodyBuilder .AppendLine(TextBox1.Text);
bodyBuilder .AppendLine(txtName.Text);
bodyBuilder .AppendLine(txtCName.Text);
bodyBuilder .AppendLine(txtAddress.Text);
  // etc.
myMail.Body = bodyBuilder .ToString();

或

将String.Format与Environment.NewLine结合使用

e、 g

您只需在Environment.NewLine的字符串中定义一个占位符，就可以重用它

result = text1 + Environment.NewLine + text2 + Environment.NewLine + text3;

这将把text1、text2和text3放在一个单独的行中

myMail.Body = TextBox1.Text + Environment.NewLine + 
                  txtName.Text+ Environment.NewLine + 
                  txtCName.Text+ Environment.NewLine + 
                  txtAddress.Text+ Environment.NewLine + 
                  TextBox1.Text+ Environment.NewLine + 
                  txtCity.Text+ Environment.NewLine + 
                  txtState.Text+ Environment.NewLine + 
                  txtCountry.Text+ Environment.NewLine + 
                  txtPhone.Text+ Environment.NewLine + 
                  Fax.Text+ Environment.NewLine + 
                  txtCell.Text+ Environment.NewLine + 
                  txtEmail.Text+ Environment.NewLine + 
                  txtPrinting.Text;
    myMail.BodyEncoding = System.Text.Encoding.UTF8;

StringBuilder bodyBuilder = new StringBuilder("");
bodyBuilder .AppendLine(TextBox1.Text);
bodyBuilder .AppendLine(txtName.Text);
bodyBuilder .AppendLine(txtCName.Text);
bodyBuilder .AppendLine(txtAddress.Text);
  // etc.
myMail.Body = bodyBuilder .ToString();

myMail.Body = String.Format("{0}{1}{2}{1}{3}{1} ... ", TextBox1.Text, Environment.NewLine, txtCName.Text, txtAddress.Text -- etc...

myMail.Body = TextBox1.Text+ Environment.NewLine +
                      txtName.Text+ Environment.NewLine +
                      txtCName.Text+ Environment.NewLine +
                      txtAddress.Text+ Environment.NewLine +
                      TextBox1.Text+ Environment.NewLine +
                      txtCity.Text+ Environment.NewLine +
                      txtState.Text+ Environment.NewLine +
                      txtCountry.Text+ Environment.NewLine +
                      txtPhone.Text+ Environment.NewLine +
                      Fax.Text+ Environment.NewLine +
                      txtCell.Text+ Environment.NewLine +
                      txtEmail.Text+ Environment.NewLine +
                      txtPrinting.Text;

String.Format("{0}{1}{2}{1}{3}", "ValueOfTextbox1", Environment.NewLine, "ValueOfTextbox2", "ValueOfTextbox3");

result = text1 + Environment.NewLine + text2 + Environment.NewLine + text3;
