Using
the static Join
method of the
string
class, the array of strings can be easily
joined in as little as one line of code. For example:
string[] infoArray = new string[5] {"11", "12", "Checking", "111", "Savings"}; string delimitedInfo = string.Join(",", infoArray);
This code sets the value of delimitedInfo
to the
following:
11,12,Checking,111,Savings
The Join
method concatenates all the strings
contained in a string array. Additionally, a specified delimiting
character(s) is inserted between each string in the array. This
method returns a single string object with the fully joined and
delimited text.
Unlike the Split
method of the
string
class, the Join
method
accepts only one delimiting character at a time. In order to use
multiple delimiting characters within a string of values, subsequent
Join
operations must be performed on the
information until all of the data has been joined together into a
single string. For example:
string[] infoArray = new string[4] {"11", "12", "Checking", "Savings"}; string delimitedInfoBegin = string.Join(",", infoArray, 0, 2); string delimitedInfoEnd = string.Join(",", infoArray, 2, 2); string[] delimitedInfoTotal = new string[2] {delimitedInfoBegin, delimitedInfoEnd}; string delimitedInfoFinal = string.Join(":", delimitedInfoTotal); Console.WriteLine(delimitedInfoFinal);
produces the following delimited file:
11,12:Checking,Savings
