Merhabalar bu kısa makalede sizlere iki DataTable nesnesini birleştirebileceğiniz (DataTable Merge DataTable) bir kod bloğu paylaşmak istiyorum.

public static DataTable MergeDataTable(this DataTable[] dataTables)        {            List<int> oList = new List<int>();            DataTable mergedDataTable = new DataTable();            foreach (DataTable dt in dataTables)            {                oList.Add(dt.Rows.Count);                foreach (DataColumn dc in dt.Columns)                {                    mergedDataTable.Columns.Add(dt.TableName + "-" + dc.ColumnName, dc.DataType);                }            }            int temp = 0;            for (int m = 0; m < oList.Count; m++)            {                for (int n = 0; n < oList.Count - 1; n++)                {                    if (oList[n] > oList[n + 1])                    {                        temp = oList[n + 1];                        oList[n + 1] = oList[n];                        oList[n] = temp;                    }                }            }            int maxRow = oList[oList.Count - 1];            for (int o = 0; o < maxRow; o++)            {                DataRow newRow = mergedDataTable.NewRow();                int mergedDataTableColumn = 0;                foreach (DataTable dt in dataTables)                {                    if (dt.Rows.Count > o)                    {                        for (int k = 0; k < dt.Columns.Count; k++)                        {                            newRow[mergedDataTableColumn] = dt.Rows[o][k];                            mergedDataTableColumn++;                        }                    }                    else                    {                        for (int k = 0; k < dt.Columns.Count; k++)                        {                            newRow[mergedDataTableColumn] = DBNull.Value;                            mergedDataTableColumn++;                        }                    }                                    }                mergedDataTable.Rows.Add(newRow);            }            return mergedDataTable;        }
