c# - 数据表从行中获取特定列

Question

我有以下内容:

//a datatable with some rows and columns lets say 5x5
var datatable = new DataTable(); 
var numberofrows = datatable.rows.count;

for (int i = 0; i < numberofrows; i++) {
 //for each row, get the 3rd column
 var cell = datatable.rows[i].???
}

如何获取每行的第 3 列？

Answer 1

第三列

var cellValue = datatable.Rows[i][2];

更好，如果你知道列名，

var cellValue = datatable.Rows[i]["column_name"];
