c# - Show 2d-array in DataGridView -

i have 2d array. want print array in datagridview throws error:

[argument outofrangeexception unhandled ]

this code

for (int j = 0; j < height; j++) {     (int = 0; < width; i++)     {             datagridview1[i, j].value = state[i, j].h;                 //state[i, j].h array              datagridview1[i, j].style.backcolor pixelcolor[i,j];             datagridview1[i, j].style.forecolor = color.gold;     } } 

as comments have pointed out, should focus on rows , cells. need build datagridview columns , populate each row cell cell.

the width of array should correspond dgv columns , height dgv rows. take following simple example:

string[,] twod = new string[,] {   {"row 0 col 0", "row 0 col 1", "row 0 col 2"},   {"row 1 col 0", "row 1 col 1", "row 1 col 2"},   {"row 2 col 0", "row 2 col 1", "row 2 col 2"},   {"row 3 col 0", "row 3 col 1", "row 3 col 2"}, };  int height = twod.getlength(0); int width = twod.getlength(1);  this.datagridview1.columncount = width;  (int r = 0; r < height; r++) {   datagridviewrow row = new datagridviewrow();   row.createcells(this.datagridview1);    (int c = 0; c < width; c++)   {     row.cells[c].value = twod[r, c];   }    this.datagridview1.rows.add(row); }
