Use linq or array.convertall to convert the string array to an integer array

When processing data in programming, it is usually necessary to convert the string array to an array. This can be implemented using

array.convertall ] method or linq select and toarray functions.

array.convertall method

The

Array.convertall

method allows you to use each element that can be used to apply to the array and return the result as a new array. To convert the string array to an integer array, you can use the following syntax: ] int [] myints = array.convertall (arr, s => int.parse (s);

int[] myInts = Array.ConvertAll(arr, s => int.Parse(s));

as a parameter. This lambda expression receives a string

to analyze it into an integer and return the conversion integer. The generated integer array is stored in Myints ] variables. linq solution or you can use Linq's select torray

to convert the string array to an array. The

Select

method will apply the conversion operation to each element of the array, and return a new array containing the conversion value.

function will be converted to array that will be generated by that will be generated. The grammar of this LINQ solution is as follows: ] int [] myints = Arr.Select (int.parse) .toarray (); In this case, the select method uses Lambda expression int.pars to analyze each element of Essence Then, the

Ienumerable

 collection of  function will be converted into an integer array that will be generated.
