Question

在我的datatable列之一中，我希望该值以双引号显示

AS： - "My value"

以下是我的代码： -

 string StrPriBody = "Dear User, <br><br> The Number of days revised by you from " +
     " " + table.Rows[0]["LAST_ACTION_DAYS"] + " days to " +
     " " + table.Rows[0]["CURRENT_ACTION_DAYS"] + " days. <br /> " +
     " with Remark <b> " + table.Rows[0]["REMARKS"] + "</b><br /><br />";

我想用双引号显示REMARK值。

如何实现？

Answer 1

使用反斜杠添加额外的引号：

string StrPriBody = "Dear User, <br><br> The Number of days revised by you from " +
     " " + table.Rows[0]["LAST_ACTION_DAYS"] + " days to " +
     " " + table.Rows[0]["CURRENT_ACTION_DAYS"] + " days. <br /> " +
     " with Remark <b> \"" + table.Rows[0]["REMARKS"] + "\"</b><br /><br />";

Answer 2

使用\在字符串中打印转义序列字符

为了更好的可读性，我会使用verbatim string literal，因为它允许避免连接并轻松扩展多行。此外，String.Format会使您的字符串更具可读性：

string StrPriBody = String.Format(@"
Dear User, 
<br><br> 
The Number of days revised by you from {0} days to {1} days. <br />
with Remark <b> ""{2}""</b>
<br /><br />",
   table.Rows[0]["LAST_ACTION_DAYS"],
   table.Rows[0]["CURRENT_ACTION_DAYS"],
   table.Rows[0]["REMARKS"]);

此外，C＃6.0（Visual Studio 2015）引入了interpolated strings，这使得字符串构造更加便于阅读：

string StrPriBody = $@"
Dear User, 
<br><br> 
The Number of days revised by you from {table.Rows[0]["LAST_ACTION_DAYS"]} days to {table.Rows[0]["CURRENT_ACTION_DAYS"]} days. <br />
with Remark <b> ""{table.Rows[0]["REMARKS"]}""</b>
<br /><br />";
