[問題] dictionary用法
請問我如果想存一個矩陣
假設矩陣是
|1 1 0|
|0 0 0|
|1 0 1|
那我宣告
Dictionary<int, Dictionary<int, int>> matrix = new Dictionary<int,
Dictionary<int, int>>();
Dictionary<int, int> col = new Dictionary<int, int>();
先將每一行存入col，再存入matrix
col.Clear();
col.Add(1, 1);
col.Add(3, 1);
matrix.Add(1, col);
e_col.Clear();
e_col.Add(1, 1);
evaluation.Add(2, e_col);
e_col.Clear();
e_col.Add(3, 1);
evaluation.Add(3, e_col);
for (int i = 1; i <= 3; i++)
{
for (int j = 1; j <= 3; j++)
{
if (matrix.ContainsKey(i))
{
if (matrix[i].ContainsKey(j))
{
Console.WriteLine(matrix[i][j]);
}
}
}
}
但輸出好像不是我想的這樣，請問各位我哪裡做錯了?
