数据网格是在 XAML 中创建的，我已经使用行数据填充了数据网格

The WPF datagrid was built to bind to something like a DataTable. The majority of the time, you will modify the DataTable, and the Rows/Columns within the DataTable that is bound to the DataGrid.
WPF 数据网格被构建为绑定到数据表之类的东西。大多数情况下，您将修改 DataTable 以及绑定到 DataGrid 的 DataTable 中的行/列。
The DataGrid itself is the Visual Element for the DataTable. Here is a pretty good tutorial on how to do this. To modify data within a loop would look something like this.
DataGrid 本身是 DataTable 的可视元素。这是一个关于如何执行此操作的非常好的教程。在循环中修改数据看起来像这样。
foreach(DataRow row in myTable.Rows)
{
row["ColumnTitle"] = 1;
}
This would simply make all the values in Column "ColumnTitle" equal to 1. To access a single cell it would look something like this.
这只会使“ColumnTitle”列中的所有值都等于 1。要访问单个单元格，它看起来像这样。
myTable.Rows[0][0] = 1;
This would set the first cell in your DataTable to 1.
这会将 DataTable 中的第一个单元格设置为 1。
