field_count

)

const

Converts the value of the current xtd::version object to its equivalent xtd::ustring representation. A specified count indicates the number of components to return.

Parameters

field_count

The number of components to return. The field_count ranges from 0 to 4.

Returns

The xtd::ustring representation of the values of the major, minor, build, and revision components of the current xtd::version object, each separated by a period character ('.'). The field_count parameter determines how many components are returned.

field_count	Return Value
0	An empty string ("").
1	major
2	major.minor
3	major.minor.build
4	major.minor.build.revision

For example, if you create xtd::version object using the constructor xtd::version(1,3,5), xtd::version::to_string(2) returns "1.3" and xtd::version::to_string(4) throws an exception.

Exceptions

xtd::argument_exception

field_count is more than 4 -or- field_count is more than the number of components defined in the current xtd::version object.
