【问题描述】：
首先，我为这篇文章的篇幅道歉，但这是我开始时所知道的一切。现在，我正在尝试使用 foreach、List<t> 和 TreeView 类以避免 SO 社区推荐的重复。
表单将通过文本框收集信息，允许通过文件对话框添加文件附件，并将所有信息整理成简洁的 HTML 正文电子邮件。我们出售平板......我的原始代码看起来有点像这样：
private void PrepareReturnEmailTwoSlabs()
{
LoadSettings();
string Fname = Properties.Settings.Default.FabricatorName;
string Facc = Properties.Settings.Default.FabricatorAccountNo;
string Fadd1 = Properties.Settings.Default.FabricatorAddress1;
string Fadd2 = Properties.Settings.Default.FabricatorAddress2;
string Ftown = Properties.Settings.Default.FabricatorTown;
string Fcounty = Properties.Settings.Default.FabricatorCounty;
string Fpostcode = Properties.Settings.Default.FabricatorPostcode;
string Fphoneno = Properties.Settings.Default.FabricatorPhone;
string Femail = Properties.Settings.Default.FabricatorEmail;
string Fclient = Properties.Settings.Default.ClientManagerEmail;
string Fcentre = Properties.Settings.Default.CentreEmail;
string FQt = Properties.Settings.Default.QTEmail;
string Dateofinv = dateTimePicker1.Value.ToShortDateString();
string Inv = textBox13.Text;
string Material1 = textBox14.Text;
string Thick1 = comboBox8.SelectedValue.ToString();
string Batch1 = textBox44.Text;
string Reason1 = comboBox1.SelectedValue.ToString();
string Notes = textBox18.Text;
string Thick2 = comboBox7.SelectedValue.ToString();
string Material2 = textBox15.Text;
string Batch2 = textBox45.Text;
string Reason2 = comboBox2.SelectedValue.ToString();
if (Thick2 == null)
{
Thick2 = "not selected";
}
if (Material2 == null)
{
Material2 = "not selected ";
}
if (Batch2 == null)
{
Batch2 = "not selected ";
}
if (Reason2 == null)
{
Reason2 = "not selected ";
}
GenerateUniqueRefReturn();
//construct email
var message = new MimeMessage();
message.From.Add(new MailboxAddress("************", "***************"));
message.To.Add(new MailboxAddress("**********", "********"));
message.Subject = "Return" + " " + Returnid;
//different message bodies dependant on how many slabs are chosen
TextPart body2 = new TextPart("html")
{
Text = @"Please See Below Information" + "<br/>" +
"<h4>Return ID: " + " " + Returnid + "</h4>" + "<br/>" +
"<b>Fabricator Name:</b>" + " " + Fname + "<br/>" + Environment.NewLine +
"<b>Account Number:</b>" + " " + Facc + "<br/>" + Environment.NewLine +
"<b>Address Line 1:</b>" + " " + Fadd1 + "<br/>" + Environment.NewLine +
"<b>Address Line 2:</b>" + " " + Fadd2 + "<br/>" + Environment.NewLine +
"<b>Town:</b>" + " " + Ftown + "<br/> " + Environment.NewLine +
"<b>County:</b>" + " " + Fcounty + "<br/>" + Environment.NewLine +
"<b>Postcode:</b>" + " " + Fpostcode + "<br/>" + Environment.NewLine +
"<b>Phone:</b>" + " " + Fphoneno + "<br/>" + Environment.NewLine +
"<b>Email:</b>" + " " + Femail + "<br/>" + Environment.NewLine + "<br/>" +
"<br/>" +
"<b>Date Of Invoice: </b>" + " " + DoI + "<br/>" +
"<b>Invoice: </b>" + " " + Inv + "<br/>" +
"<b>Material Information:</b>" + "<br/>" +
//slab 1
"<b>Thickness: </b>" + " " + Thick1 + "mm" + "<br/>" +
"<b>Material Name: </b>" + " " + Material1 + "<br/>" +
"<b>Batch No: </b>" + " " + Batch1 + "<br/>" +
"<b>Reason for Return: </b>" + " " + Reason1 + "<br/>" + "<br/>" +
//slab 2
"<b>Thickness: </b>" + " " + Thick2 + "mm" + "<br/>" +
"<b>Material Name: </b>" + " " + Material2 + "<br/>" +
"<b>Batch No: </b>" + " " + Batch2 + "<br/>" +
"<b>Reason for Return: </b>" + " " + Reason2 + "<br/>" + "<br/>" +
"<br/>" +
"<b>Notes:" + " " + Notes
};
var builder = new BodyBuilder();
//check for return attachment and if found, assign attachment to message via bodybuilder
if (checkBox5.Checked)
{
builder.TextBody = body2.Text;
builder.HtmlBody = body2.Text;
builder.Attachments.Add(ReturnAttachment1);
message.Body = builder.ToMessageBody();
}
if (checkBox7.Checked)
{
builder.TextBody = body2.Text;
builder.HtmlBody = body2.Text;
builder.Attachments.Add(ReturnAttachment1);
builder.Attachments.Add(ReturnAttachment2);
message.Body = builder.ToMessageBody();
}
if (checkBox6.Checked)
{
builder.TextBody = body2.Text;
builder.HtmlBody = body2.Text;
builder.Attachments.Add(ReturnAttachment1);
builder.Attachments.Add(ReturnAttachment2);
builder.Attachments.Add(ReturnAttachment3);
message.Body = builder.ToMessageBody();
}
else
{
message.Body = body2;
}
//Connection to SMTP and Criteria to Send
using (var client = new SmtpClient())
{
// For demo-purposes, accept all SSL certificates (in case the server supports STARTTLS)
client.ServerCertificateValidationCallback = (s, c, h, e) => true;
client.Connect("smtp.gmail.com", 587, false);
// Note: only needed if the SMTP server requires authentication
client.Authenticate("***************@********.com", "*********");
client.Send(message);
client.Disconnect(true);
此代码一直重复到五个平板。所以现在，我有一个类：
{
public string Thickness { get; set; }
public string Material { get; set; }
public string Batch { get; set; }
public Slab(string Thick, string Mat, string Batchno)
{
Thickness = Thick;
Material = Mat;
Batch = Batchno;
}
}
包含此对象的列表：
private void button1_Click(object sender, EventArgs e)
{
string t = comboBox1.SelectedValue.ToString();
string m = comboBox2.SelectedValue.ToString();
string b = textBox6.Text;
Slab S = new Slab(t, m, b);
allSlabs.Add(S);
PaintTree();
}
public void PaintTree()
{
int ParentIndex;
TreeSlabs.Nodes.Clear();
foreach (Slab slab in allSlabs)
{
TreeSlabs.BeginUpdate();
TreeSlabs.Nodes.Add("Slab" + " " + (allSlabs.IndexOf(slab) + 1).ToString());
ParentIndex = allSlabs.IndexOf(slab);
TreeSlabs.Nodes[ParentIndex].Nodes.Add("Thickness: " + $"{slab.Thickness}");
TreeSlabs.Nodes[ParentIndex].Nodes.Add("Material: " + $"{slab.Material}");
TreeSlabs.Nodes[ParentIndex].Nodes.Add("Batch: " + $"{slab.Batch}");
TreeSlabs.EndUpdate();
}
}
现在我想创建一个 foreach.. 遍历每个节点.. 并从父级及其子级 foreach 节点收集信息，并以某种方式为每个节点实例化新的 HTML 方法..
Foreach 节点： 编写 HTML 行 - 新 HTML
板 1： 厚度： 材料 批次
平板 2：...等
如果有 8 个节点，它会生成 8 个这样的实体。我可以想办法……但我知道，根据我在那里阅读和看到的内容，它们肯定不是正确的方法。
非常感谢
【问题讨论】：
-
var builder = new BodyBuilder();让我开心 ;) -
我想补充一点，我错过了。我将平板对象存储在 List
中，TreeView 从中提取数据。但是我 +1 了索引..这使得将其映射回该列表有点棘手。所以我想我会从树视图生成电子邮件，而不是写回更改。我可以实例化一个 html 脚本来生成每个平板并将其自身添加到正文中吗？ -
我不知道为什么我是那个菜鸟????????♂️
-
旁注，
Add($"Batch: {slab.Batch}")更接近于Add("Batch: " + $"{slab.Batch}")
