如何使用带有定界符的数组? [英] How to use array with delimiters?

问题描述

我想使用数组来获取联系人的电子邮件，以便可以大量发送电子邮件.
&我还需要使用定界符来用分号分隔每封电子邮件；
之后，我需要再次将它们重新连接为字符串，以将其存储到文本框中.
我不知道代码看起来如何.

有没有要遵循的教程或步骤，以便我可以学习如何使用数组和定界符?

我是编码的新手，因此需要紧急帮助.谢谢

I want to use array to get the contacts'' email so that I can send out the email as mass amount.
& I need to also use delimiters to separate each of the emails with a semi-colon ;

I have no idea how the codes look like.

Is there any tutorials or steps to follow so that I can learn how to use array and delimiters?

推荐答案

据我了解，需要将emailIds 存储在array 中，然后需要构建string 与emailIds 和; as delimiter.一起使用，如果可以，则可以使用以下代码.

As I understand from the question, it is required to store the emailIds in an array and then it is required to build a string with those emailIds using ; as delimiter. If it is so, then the following code can be used.

string[] emailIds = new string[] {"[e-mail]", "[e-mail]", "[e-mail]"};
string emailIdsString = string.Join("; ", emailIds);
Console.WriteLine (emailIdsString);

//[e-mail]; [e-mail]; [e-mail]

SQL Server不知道BOOLEAN数据类型.请参阅可用的数据类型 [TRUE"的电子邮件，请使用以下查询:

SQL Server does not know BOOLEAN data type. See availible DataTypes[^] for MS SQL Server. BOOLEAN is a text!
So... If you would like to get emails where newsletterAgree is set to "TRUE", use this query:

SELECT Email
FROM Customer
WHERE newsletterAgree = 'True'

我建议您更改int的newsletterAgree字段的数据类型，其中
0 = False
和
-1 = TRUE

I recomend you to change the data type for newsletterAgree field for int, where
0 = False
and
-1 = TRUE
