C# How to wrap date string in single quote inside the string's double quotes

Question

I am trying to wrap my DateTime's date format in single quotes

eg DateTime.Now().ToString("yyyy-MM-dd") output will be like "2017-03-30"

My question, Is there anyway of producing the result like "'2017-03-30'" (ie single quotes within the double quotes)?

Answer 1

Use string.Format , or on C#6+ string interpolation :

// String format
string.Format("'{0}'", DateTime.Now.ToString("yyyy-MM-dd"));

// Interpolation
$"'{DateTime.Now.ToString("yyyy-MM-dd")}'";

Result:

'2017-03-30'

Answer 2

尝试使用string.Format ：

string.Format("'{0:yyyy-MM-dd}'", DateTime.Now)
