[c#] Get Cell Value from a DataTable in C#

Here is a DataTable dt, which has lots of data.

I want to get the specific Cell Value from the DataTable, say Cell[i,j]. Where, i -> Rows and j -> Columns. I will iterate i,j's value with two forloops.

But I can't figure out how I can call a cell by its index.

Here's the code:

for (i = 0; i <= dt.Rows.Count - 1; i++)
{
    for (j = 0; j <= dt.Columns.Count - 1; j++)
    {
        var cell = dt.Rows[i][j];
        xlWorkSheet.Cells[i + 1, j + 1] = cell;
    }
}

If I have understood your question correctly you want to display one particular cell of your populated datatable? This what I used to display the given cell in my DataGrid.

var s  = dataGridView2.Rows[i].Cells[j].Value;
txt_Country.Text = s.ToString();

Hope this helps

You can iterate DataTable like this:

private void button1_Click(object sender, EventArgs e)
{
    for(int i = 0; i< dt.Rows.Count;i++)
        for (int j = 0; j <dt.Columns.Count ; j++)
        {
            object o = dt.Rows[i].ItemArray[j];
            //if you want to get the string
            //string s = o = dt.Rows[i].ItemArray[j].ToString();
        }
}

Depending on the type of the data in the DataTable cell, you can cast the object to whatever you want.

You probably need to reference it from the Rowsrather than as a cell:

var cellValue = dt.Rows[i][j];

You can call the indexer directly on the datatable variable as well:

var cellValue = dt[i].ColumnName

To get cell column name as well as cell value :

List<JObject> dataList = new List<JObject>();

for (int i = 0; i < dataTable.Rows.Count; i++)
{
    JObject eachRowObj = new JObject();

    for (int j = 0; j < dataTable.Columns.Count; j++)
    {
        string key = Convert.ToString(dataTable.Columns[j]);
        string value = Convert.ToString(dataTable.Rows[i].ItemArray[j]);

        eachRowObj.Add(key, value);

    }

    dataList.Add(eachRowObj);

}
