将datatable值获取到另一个datatable

DataTable sourceTable = // 源datatable
DataTable targetTable = new DataTable(); // 目标datatable

// 复制源datatable的结构到目标datatable
foreach (DataColumn column in sourceTable.Columns)
{
    targetTable.Columns.Add(column.ColumnName, column.DataType);
}

// 复制源datatable的数据到目标datatable
foreach (DataRow row in sourceTable.Rows)
{
    DataRow newRow = targetTable.NewRow();
    newRow.ItemArray = row.ItemArray;
    targetTable.Rows.Add(newRow);
}

DataTable sourceTable = // 源datatable
DataTable targetTable = new DataTable(); // 目标datatable

// 复制源datatable的结构到目标datatable
for (DataColumn column : sourceTable.getColumns()) {
    targetTable.getColumns().add(new DataColumn(column.getColumnName(), column.getDataType()));
}

// 复制源datatable的数据到目标datatable
for (DataRow row : sourceTable.getRows()) {
    DataRow newRow = new DataRow();
    newRow.setItemArray(row.getItemArray());
    targetTable.getRows().add(newRow);
}
