This Row already belongs to another table error when trying to add rows?

Question

I have a DataTable which has some rows and I am using the select to filter the rows to get a collection of DataRows which I then loop through using foreach and add it to ano

Answer 1

yourTable.ImportRow(dataRow);

It's because the row you're copying doesn't have the same TableName:

For example, try:

Table1.TableName = "Table1";
Table2.TableName = "Table2";
