Writing an array to a file

[tivicoo]

The data is created via a function generator, which is connected to a Data Acquisition Board (DAQ Board). 4000 data points were collected, and an array called ADData was generated to hold the data values. I am trying to save ADData, which is the array holding the 16-bit data values.

I have been using different strategies to save (human readable) data into a text file, file the output is always:

System.UInt16[]

Any ideas on how to save my data?

I'm going to move this to the .NET Forums where the resident experts can better assist you.

Please use thread titles that best describe your problem. That challenges thing is an old trick which is a no no these days.
Post the code you used to print. Hopefully you did not print the array instead of the array contents ...

In this case ADData is an array of type System.UInt16.
So it's declaration would probably look like:
UInt16[] ADData;

But regardless, you need to loop through it, try this:

//this will loop through each entry in the ADData array
for (int i=0; i<ADData.Length;i++)
{
   Uint16 val= ADData[i];
   //write this value to a file
}
 

You can also use a loop style like this:

foreach(Uint16 val in ADData)
{
   // val contains the current value
   // write this value to a file
}
 

So you would probably want something like this psuedo code:
Open file for writing data
Use one of the looping methods expressed above, writing each value to the file
Close the file (and filestream)

How about making a generic Print method for all arrays?
In Java we have a neat Arrays.toString(T[] a). I suppose writing a generic one in C# should be a breeze
