Question

I want to pass an array of arrays to another Form

String[] arrayOfStrings = new String[4];
arrayOfStrings[0] = td1stcolumn[];
arrayOfStrings[1] = td2ndcolumn[];
arrayOfStrings[2] = td3rdcolumn[];
arrayOfStrings[3] = td4thcolumn[];
string resultDialogString = ResultDialog.ShowBox(arrayOfStrings, "Result Page");

td1stcolumn, td2ndcolumn, td3rdcolumn and td4thcolumn are all String arrays

C# is expecting values in the [] for td…column

Signature of ResultDialog.ShowBox is

public static string ShowBox(string[] arrayOfMessages, string txtTitle)

but I can modify the signature. I just need to transfer the data from the

td1stcolumn, td2ndcolumn, td3rdcolumn and td4thcolumn

to the ResultDialog.Show method

Answer 1

Assuming you have declared your “td” variables like this:

string[] td1stcolumn;
string[] td2ndcolumn;
string[] td3rdcolumn;
string[] td4thcolumn;

Then you can assign these values to your arrayOfStrings like this:

arrayOfStrings[0] = td1stcolumn;
arrayOfStrings[1] = td2ndcolumn;
arrayOfStrings[2] = td3rdcolumn;
arrayOfStrings[3] = td4thcolumn;

You’ll also need to change the declaration for your string array to something like this:

// an array of arrays.  Each array must be the same length.
// your situation calls for a jagged array though.
string[,] arrayOfStrings;

or

// jagged array. each array can be of varying length.
string[][] arrayOfSTrings;

Jagged Array Documentation

Example of a Jagged Array usage:

string[][] arr = new string[2][];

arr[0] = new [] {"a", "b", "c", "d"};
arr[1] = new [] {"a", "b", "c", "d"};
