c# - Input string not in the correct format when reading a text file into a 2d Array -

i trying read text file 2d array. error of

input string not in correct format.

i have checked text file , should , cant see why error happening?

        int[,] numbermatrix = new int[10, 10];         string[] split = null;          (int rowcount = 1; rowcount < 11; rowcount++)         {             int[] temp1darray = new int[10];             string filelocation = "c:\\week10\\one.txt";             string textfile = file.readalltext(filelocation);              (int columncount = 1; columncount < 11; columncount++)             {                 string delimstr = " ";                 char[] delimiter = delimstr.tochararray();                 //string filelocation = "c:\\week10\\1-100.txt";                 //string textfile = file.readalllines(filelocation);                 (int x = 0; x <= 10; x++)                 {                     split = textfile.split(delimiter, x);                 }             }              (int rowcount1 = 1; rowcount1 < 11; rowcount1++)             {                 (int columncount = 1; columncount < 11; columncount++)                 {                     numbermatrix[rowcount1 - 1, columncount - 1]   =convert.toint32(split.elementat(columncount - 1));                 }             }         }          (int rowcount = 10; rowcount > 0; rowcount--)         {             (int columncount = 10; columncount > 0; columncount--)             {                 console.writeline(numbermatrix[rowcount - 1, columncount - 1]);             }         }     } 

so ok, haven't provided file contents , exact exception description (it can fire on reason possible). can give more simple implementation file parsing. can't think of answer, magically find reason of why 1 number in file can't parsed int

string[] lines = file.readalllines(@"c:\temp\1.txt"); var options = stringsplitoptions.removeemptyentries;  int[][] numbers = lines.select(line => line.split(new[]{' '}, options)                                            .select(int.parse)                                            .toarray())                        .toarray();  console.writeline(string.join(environment.newline,                                numbers.select(n => string.join(" ", n)))); 

for file:

1 10 20 30  4234 35 123 543 42 54 345 645 

prints:

1 10 20 30 4234 35 123 543 42 54 345 645 

if need rectangle array int[,] use next code parse to.

int [,] numbersrect = new int[numbers.length, numbers[0].length];  (int = 0; < numbersrect.getlength(0); i++) {     (int j = 0; j < numbersrect.getlength(1); j++)     {         numbersrect[i,j] = numbers[i][j];     } }
