1. interpolation string
$ text identifies special character string is not a string interpolation, the interpolation expression may contain string text.
Parse the string to the string interpolation result string, inserted in the expression with the result of the expression is replaced item representation.
Use a higher priority in C # 6 language versions
interpolation provided in the string syntax more readable and easier
2. The structure of the interpolation string
before the string $ sign, and with no spaces between $ "
structure: {<interpolationExpression> [, < alignment>] [: <formatString>]}
Parameters:
interpolationExpression: generating the need to set an expression result format
alignment: constant expression, interpolation result of its expression that defines the value represents a minimum number of characters in a string form of the value, if positive, the string representation is right-aligned; if the value. is negative, for the left-justified
formatString: format string types supported by the results of expression
3. the special character
to the interpolation generated text strings included in braces "{" or "}", use two braces , i.e., "{{" or "}}"
colon ( ":") in the interpolation string has a special meaning, or using conditional expressions, conditional expressions in parentheses
verbatim interpolated character string $ at the beginning, followed by the character @
4 and designated IFormatProvider implicit conversion achieved
interpolation string into a string instance
interpolation string into a compound represented by the format string FormattableStri ng example, expression result format will also
be converted to a string interpolation instance IFormattable
