How can I print the contents of an array horizontally

Question

Why doesn t the console window print the array contents horizontally rather than vertically   Is there a way to change that   How can I display the content of my array horizontally instead of vertically  with a Console WriteLine     For example   int   numbers   new int 100  for int i  i  lt  100  i          numbers i    i     for  int i  i  lt  100  i          Console WriteLine numbers i

The below solution is the simplest one   Console WriteLine    0     string Join       array      Output   1  2  3  4  5    Another short solution   Array ForEach array   val   gt  Console Write   0     val      Output  1 2 3 4 5  Or if you need to add add    use the below   int i   0  Array ForEach array   val   gt  Console Write i    array Length -1      0       0      val      Output  1  2  3  4  5

Just loop through the array and write the items to the console using Write instead of WriteLine   foreach var item in array      Console Write item ToString             As long as your items don t have any line breaks  that will produce a single line      or  as Jon Skeet said  provide a little more context to your question

Using Console Write only works if the thread is the only thread writing to the Console  otherwise your output may be interspersed with other output that may or may not insert newlines  as well as other undesired characters   To ensure your array is printed intact  use Console WriteLine to write one string   Most any array of objects can be printed horizontally  depending on the type s ToString   method  using the non-generic Join available before  NET 4 0           int   numbers   new int 100           for int i  0  i  lt  100  i                          numbers i    i                       For clarity         IEnumerable strings   numbers Select lt int  string gt  j  gt j ToString             string   stringArray   strings ToArray lt string gt             string output   string Join       stringArray           Console WriteLine output              OR             For brevity         Console WriteLine string Join       numbers Select lt int  string gt  j   gt  j ToString    ToArray lt string gt

If you need to pretty print an array of arrays  something like this could work  Pretty Print Array of Arrays in  NET C   public string PrettyPrintArrayOfArrays int     arrayOfArrays      if  arrayOfArrays    null      return        var prettyArrays   new string arrayOfArrays Length      for  int i   0  i  lt  arrayOfArrays Length  i            prettyArrays i          String Join      arrayOfArrays i                 return       String Join      prettyArrays             Example Output     2 3      2 3   5 4 3      2 3   5 4 3   8 9

You are probably using Console WriteLine for printing the array    int   array   new int     1  2  3    foreach var item in array        Console WriteLine item ToString         If you don t want to have every item on a separate line use Console Write   int   array   new int     1  2  3    foreach var item in array        Console Write item ToString         or string Join lt T gt   in  NET Framework 4 or later    int   array   new int     1  2  3    Console WriteLine string Join      array

I would suggest   foreach var item in array    Console Write   0    item     As written above  except it does not raise an exception if one item is null   Console Write string Join      array      would be perfect if the array is a string
