DataGridView Column Data to Array

问题

Is it possible to transfer all data from a DataGridView column to string[] array ?

Here is my code so far, unfortunately, it can't convert DataGridViewRow to int

foreach (DataGridViewRow dgvrows in dgvDetail.Rows)
{
   array[dgvrows] = dgvDetail.Rows[dgvrows].Cell[3].value.ToString().Trim;
}

You can do it in various ways:

• Use a normal for-loop. The foreach is only syntactic sugar, the real work is always done with the good old for-loop.

• Use foreach and the DataGridViewRow.Index property to set the array index.

• Use LINQ to create the array

for (int i = 0; i < dgvDetail.Rows.Count; i++)
{
    array[i] = dgvDetail.Rows[i].Cells[3].Value.ToString().Trim();
}   


foreach (DataGridViewRow row in dgvDetail.Rows) 
{
    array[row.Index] = row.Cell[3].Value.ToString().Trim();
}


var array = dgvDetail.Rows
    .Cast<DataGridViewRow>()
    .Select(x => x.Cells[3].Value.ToString().Trim())
    .ToArray();

Note that in both loops you need to initialize the array first!
