本文介绍了发送表中的电子邮件的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一个要求,发送一个查询结果的电子邮件。我使用两种方法:
GetDataTable():执行查询和获取数据表(这需要以电子邮件发送)
SendAutomatedEmail():发送自动电子邮件
问题:我需要发送的数据表或HTML表中的电子邮件,类似下面code。这工作正常的字符串代替DataTable的
公共静态无效的主要(字串[] args)
{
数据表数据表= GetDataTable();
SendAutomatedEmail(数据表);
}
公共静态数据表GetDataTable(字符串的CommandText)
{
字符串cnString = ConfigurationManager.ConnectionStrings [连接2]的ConnectionString。
的SqlConnection的SqlConnection =新的SqlConnection(cnString);
字符串的CommandText =SELECT * FROM dbo.fs010100(NOLOCK);
的SqlCommand的SqlCommand =新的SqlCommand(CommandText中,SqlConnection的);
SqlDataAdapter的SqlDataAdapter的=新System.Data.SqlClient.SqlDataAdapter();
sqlDataAdapter.SelectCommand = SqlCommand的;
DataTable中的dataTable =新的DataTable();
dataTable.Locale = System.Globalization.CultureInfo.InvariantCulture;
//添加或刷新行的数据集,以匹配数据源中的
尝试
{
sqlDataAdapter.Fill(dataTable的);
在SQLConnection.close(dataTable的);
}
赶上(例外_Exception)
{
在SQLConnection.close();
//Console.WriteLine(_Exception.Message);
返回null;
}
返回的dataTable;
}
公共静态无效SendAutomatedEmail(DataTable的DT,串收件人=user@domain.com)
{
尝试
{
字符串的邮件服务器=server.com;
MailMessage消息=新MailMessage(
it@domain.com
接受者,
测试电子邮件,
dt.ToString()
);
SmtpClient客户端=新SmtpClient(邮件服务器);
VAR AuthenticationDetails =新的NetworkCredential(user@domain.com,密码);
client.Credentials = AuthenticationDetails;
client.Send(消息);
}
赶上(例外五)
{
}
}
解决方案
好了,现在试试这个:
公共静态无效的主要(字串[] args)
{
数据集的数据集= getDataSet();
字符串htmlString = getHtml(数据集);
SendAutomatedEmail(htmlStringemail@domain.com);
}
公共静态数据集getDataSet(字符串的CommandText)
{
字符串cnString = ConfigurationManager.ConnectionStrings [连接2]的ConnectionString。
的SqlConnection的SqlConnection =新的SqlConnection(cnString);
字符串的CommandText =SELECT * FROM dbo.fs010100(NOLOCK);
的SqlCommand的SqlCommand =新的SqlCommand(CommandText中,SqlConnection的);
SqlDataAdapter的SqlDataAdapter的=新System.Data.SqlClient.SqlDataAdapter();
sqlDataAdapter.SelectCommand = SqlCommand的;
数据集的数据集=新的DataSet();
尝试
{
sqlDataAdapter.Fill(数据集,头);
在SQLConnection.close();
}
赶上(例外_Exception)
{
在SQLConnection.close();
返回null;
}
返回的数据集;
}
公共静态字符串getHtml(数据集数据集)
{
尝试
{
串消息体=&其中;字体>将以下是记录:其中; /字体>&所述峰; br>&所述峰; br>中;
如果(dataSet.Tables [0] .Rows.Count == 0)
返回消息体;
字符串htmlTableStart =<表格样式= \边界崩溃:崩溃;文本对齐:中心; \>中;
字符串htmlTableEnd =< /表>;
字符串htmlHeaderRowStart =< TR风格= \背景颜色:#6FA1D2;颜色:#FFFFFF; \>中;
串htmlHeaderRowEnd =&其中; / TR>中;
字符串htmlTrStart =< TR风格= \颜色:#555555; \>中;
串htmlTrEnd =&其中; / TR>中;
字符串htmlTdStart =< TD风格= \边框颜色:#5c87b2;边框风格:固体;边框宽度:薄;填充:5px的; \>中;
串htmlTdEnd =&其中; / TD>中;
消息体+ = htmlTableStart;
消息体+ = htmlHeaderRowStart;
消息体+ = htmlTdStart +列1+ htmlTdEnd;
消息体+ = htmlHeaderRowEnd;
的foreach(DataRow中排在notShippedDataSet.Tables [0] .Rows)
{
消息体=消息体+ htmlTrStart;
消息体=消息体+ htmlTdStart +行[字段名] + htmlTdEnd;
消息体=消息体+ htmlTrEnd;
}
消息体=消息体+ htmlTableEnd;
返回消息体;
}
赶上(例外前)
{
返回null;
}
}

I have a requirement to send the results of a query in emails. I am using two methods:
GetDataTable() : to execute the query and obtain datatable(which needs to be sent in email)
SendAutomatedEmail() : to send automated emails.
Problem: i need to send data table or html table in email, something like code below. this works fine for a string in place of dataTable
public static void Main(string[] args)
{
DataTable datatable = GetDataTable();
SendAutomatedEmail(datatable );
}
public static DataTable GetDataTable(string CommandText)
{
string cnString = ConfigurationManager.ConnectionStrings["Connection2"].ConnectionString;
SqlConnection sqlConnection = new SqlConnection(cnString);
string CommandText = "select * from dbo.fs010100 (nolock)";
SqlCommand sqlCommand = new SqlCommand( CommandText, sqlConnection);
SqlDataAdapter sqlDataAdapter = new System.Data.SqlClient.SqlDataAdapter();
sqlDataAdapter.SelectCommand = sqlCommand;
DataTable dataTable = new DataTable();
dataTable.Locale = System.Globalization.CultureInfo.InvariantCulture;
// Adds or refreshes rows in the DataSet to match those in the data source
try
{
sqlDataAdapter.Fill(dataTable);
sqlConnection.Close(dataTable );
}
catch (Exception _Exception)
{
sqlConnection.Close();
//Console.WriteLine(_Exception.Message);
return null;
}
return dataTable;
}
public static void SendAutomatedEmail(DataTable dt, string recipient = "user@domain.com")
{
try
{
string mailServer = "server.com";
MailMessage message = new MailMessage(
"it@domain.com",
recipient,
"Test Email",
dt.ToString()
);
SmtpClient client = new SmtpClient(mailServer);
var AuthenticationDetails = new NetworkCredential("user@domain.com", "password");
client.Credentials = AuthenticationDetails;
client.Send(message);
}
catch (Exception e)
{
}
}
解决方案
ok, try this now:
public static void Main(string[] args)
{
DataSet dataSet = getDataSet();
string htmlString= getHtml(dataSet);
SendAutomatedEmail(htmlString, "email@domain.com");
}
public static DataSet getDataSet(string CommandText)
{
string cnString = ConfigurationManager.ConnectionStrings["Connection2"].ConnectionString;
SqlConnection sqlConnection = new SqlConnection(cnString);
string CommandText = "select * from dbo.fs010100 (nolock)";
SqlCommand sqlCommand = new SqlCommand( CommandText, sqlConnection);
SqlDataAdapter sqlDataAdapter = new System.Data.SqlClient.SqlDataAdapter();
sqlDataAdapter.SelectCommand = sqlCommand;
DataSet dataSet = new DataSet();
try
{
sqlDataAdapter.Fill(dataSet, "header");
sqlConnection.Close();
}
catch (Exception _Exception)
{
sqlConnection.Close();
return null;
}
return dataSet;
}
public static string getHtml(DataSet dataSet)
{
try
{
string messageBody = "<font>The following are the records: </font><br><br>";
if (dataSet.Tables[0].Rows.Count == 0)
return messageBody;
string htmlTableStart = "<table style=\"border-collapse:collapse; text-align:center;\" >";
string htmlTableEnd = "</table>";
string htmlHeaderRowStart = "<tr style =\"background-color:#6FA1D2; color:#ffffff;\">";
string htmlHeaderRowEnd = "</tr>";
string htmlTrStart = "<tr style =\"color:#555555;\">";
string htmlTrEnd = "</tr>";
string htmlTdStart = "<td style=\" border-color:#5c87b2; border-style:solid; border-width:thin; padding: 5px;\">";
string htmlTdEnd = "</td>";
messageBody+= htmlTableStart;
messageBody += htmlHeaderRowStart;
messageBody += htmlTdStart + "Column1 " + htmlTdEnd;
messageBody += htmlHeaderRowEnd;
foreach (DataRow Row in notShippedDataSet.Tables[0].Rows)
{
messageBody = messageBody + htmlTrStart;
messageBody = messageBody + htmlTdStart + Row["fieldName"] + htmlTdEnd;
messageBody = messageBody + htmlTrEnd;
}
messageBody = messageBody + htmlTableEnd;
return messageBody;
}
catch (Exception ex)
{
return null;
}
}
public static void SendAutomatedEmail(string htmlString, string recipient = "user@domain.com")
{
try
{
string mailServer = "server.com";
MailMessage message = new MailMessage("it@domain.com", recipient);
message .IsBodyHtml = true;
message .Body = htmlString;
message .Subject = "Test Email";
