用Spire.doc来合并邮件
让我们想象一下这样的场景：你在一家IT公司上班。某天公司的某一产品大幅度升级了。然后你需要通知所有的客户。这真是很长的名单。一个个的通知他们是有点蠢的，因为这要花费太多的时间和人力了。为什么不找个更好的方法来快速高效地完成这项工作呢？我这里给大家一个用组件来解决的方法。组件的链接在这里。这是Spire.doc的另一个小功能，就是用它来合并邮件。
这是一个通知邮件并且所发的内容都是相同的。首先我们先创建一个模板，这个模板是用来创建通知邮件。请看下面的模板。
接下来我们要做的是将方括号内的文本替换成客户信息。下面是实现的代码：
private int lastIndex = 0;
private void button1_Click(object sender, EventArgs e)
{
//create word document
Document document = new Document();
document.LoadFromFile("template.doc");
lastIndex = ;
//informaton of customers
List<CustomerRecord> customerRecords = new List<CustomerRecord>();
CustomerRecord c1 = new CustomerRecord();
c1.ContactName = "Lucy";
c1.Fax = "786-324-10";
c1.Date = DateTime.Now;
customerRecords.Add(c1);
CustomerRecord c2 = new CustomerRecord();
c2.ContactName = "Lily";
c2.Fax = "779-138-13";
c2.Date = DateTime.Now;
customerRecords.Add(c2);
CustomerRecord c3 = new CustomerRecord();
c3.ContactName = "James";
c3.Fax = "363-287-02";
c3.Date = DateTime.Now;
customerRecords.Add(c3);
//execute mailmerge
document.MailMerge.MergeField += newMergeFieldEventHandler(MailMerge_MergeField);
document.MailMerge.ExecuteGroup(new MailMergeDataTable("Customer", customerRecords));
//save doc file.
document.SaveToFile("result.doc", FileFormat.Doc);
//viewer the result file.
System.Diagnostics.Process.Start("result.doc");
}
void MailMerge_MergeField(object sender, MergeFieldEventArgs args)
{
//next row
if (args.RowIndex > lastIndex)
{
lastIndex = args.RowIndex;
AddPageBreakForMergeField(args.CurrentMergeField);
}
}
void AddPageBreakForMergeField(IMergeField mergeField)
{
//find position of needing to add page break
bool foundGroupStart = false;
Paragraph paramgraph = mergeField.PreviousSibling.Owner as Paragraph;
MergeField merageField = null;
while (!foundGroupStart)
{
paramgraph = paramgraph.PreviousSibling as Paragraph;
for (int i = ; i < paramgraph.Items.Count; i++)
{
merageField = paramgraph.Items[i] as MergeField;
if ((merageField != null) && (merageField.Prefix == "GroupStart"))
{
foundGroupStart = true;
break;
}
}
}
paramgraph.AppendBreak(BreakType.PageBreak);
}
//class to represent customers
public class CustomerRecord
{
private string m_contactName;
public string ContactName
{
get
{
return m_contactName;
}
set
{
m_contactName = value;
}
}
private string m_fax;
public string Fax
{
get
{
return m_fax;
}
set
{
m_fax = value;
}
}
private DateTime m_date;
public DateTime Date
{
get
{
return m_date;
}
set
{
m_date = value;
}
}
}
