SQL自動遞增列如何DataTable中

Question

SqlBulkCopy sqlBulk = new SqlBulkCopy(conn, SqlBulkCopyOptions.KeepIdentity, t); 
sqlBulk.DestinationTableName = DestTableName; 
sqlBulk.BatchSize = 1000; 
sqlBulk.WriteToServer(dt);     
t.Commit(); 

錯誤分配，如果我給你我的身份列值，如果我沒有指定它說：「空不是主鍵允許」列 - 怎麼辦？

OR

using (var bulkCopy = new SqlBulkCopy(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString, SqlBulkCopyOptions.KeepNulls & SqlBulkCopyOptions.KeepIdentity)) 
       { 
        bulkCopy.BatchSize = (int)DetailLines; 
        bulkCopy.DestinationTableName = "dbo.myTable"; 
        bulkCopy.ColumnMappings.Clear(); 
        bulkCopy.ColumnMappings.Add("SourceColumnName", "DestinationColumnName"); 
        bulkCopy.ColumnMappings.Add("SourceColumnName", "DestinationColumnName"); 


        bulkCopy.WriteToServer(datatable); 
       }
