Question

Decimal[] num=new decimal[100100]; This is element of 2darray 1 2 3 4 5 6 7 8 9 10 11 12 now i am want to convert it in one dimensional array 1 4 7 10 2 5 8 11 3 6 9 12 like this how to do? please help me

Thanks for reply but this is not as per my requirements. My requirement is decimal[] num={{123}{456}{789}{101112}} and now i want to convert it in to one dimensional array decimal[] num1={147102581136912} like this. Please help me and reply

First to clarify that I have properly understood your requirement I think you want all second dimension values together like: first dimension second dimension value 0 0 10 0 1 20 1 0 30 1 1 40 2 0 50 2 1 60 You want all second dimension 0 first then all 1 like 10 30 50 20 40 60 If this is your requirement then you can achieve by following code which is console project in C#: //declarations int firstDimention = 3; int secondDimention = 4; int [] twoDimArray = new int [firstDimention secondDimention]; int valueProvider = 1; Random numberGenerator = new Random(20); //print header Console.WriteLine( first dimension .PadRight(20) + 	 + second dimension .PadRight(20) + 	 + Value .PadRight(20)); //let's populate Array with some values for ( int firstIndex = 0; firstIndex { for ( int secondIndex = 0; secondIndex { twoDimArray[firstIndex secondIndex] = valueProvider * numberGenerator.Next(15555); valueProvider++; Console.WriteLine(firstIndex.ToString().PadRight(20) + 	 + secondIndex.ToString().PadRight(20) + 	 + twoDimArray[firstIndex secondIndex].ToString().PadRight(20)); } } Console.WriteLine(Environment.NewLine); Console.WriteLine(Environment.NewLine); //Get two dimentional values in one dimentional array int [] oneDimArray = new int [firstDimention * secondDimention]; int oneDimIndex = 0; for ( int secondIndex = 0; secondIndex { for ( int firstIndex = 0; firstIndex { oneDimArray[oneDimIndex] = twoDimArray[firstIndex secondIndex]; oneDimIndex++; } } //print header Console.WriteLine( first dimension .PadRight(20) + 	 + Value .PadRight(20)); for (oneDimIndex = 0; oneDimIndex { Console.WriteLine(oneDimIndex.ToString().PadRight(20) + 	 + oneDimArray[oneDimIndex].ToString().PadRight(20)); } Console.ReadKey(); Here is the console output:
