How to implement string[] into string[] in C#?

Question

I want to implement 'string[] loadedText' into 'string[] dataList', but I keep getting an error saying "Cannot implicitly convert type 'string[]' to 'string'".

string[] dataList = new string[1800];
StreamReader loadNewData = new StreamReader("podaciB.txt");
int i = 0;
while (i < 1800)
{
    string[] loadedData = loadNewData.ReadLine().Split(';');
    dataList[i] = loadedData;
    i++;
}

I need the 'dataList' array that will contain 1800 'loadedData' arrays which contain 4 strings in them.

your loadedData is an array of string and dataList as well. But when you access dataList[i] you are in a string right now and compiler waiting a string to assign it. — darcane

What you need is a jagged array:

string[][] dataList = new string[1800][];

loadNewData.ReadLine().Split(';'); returns array of string and you are storing array of strings into dataList[i] i.e. string element of string array. This is the reason behind error which you mentioned in your question

If you want to store loadNewData.ReadLine().Split(';'); into an array then I would suggest you to use nested list List<List<string>>

Something like,

List<List<string>> dataList = List<List<string>>();
StreamReader loadNewData = new StreamReader("podaciB.txt");
int i = 0;
while (i < 1800)
{
    var innerList = loadNewData.ReadLine().Split(';').ToList();
    dataList.Add(innerList);
    i++;
}

It seems you need an array of array of strings, something like string[][].

You can do it like this:

string[][] dataList = new string[1800][];
StreamReader loadNewData = new StreamReader("podaciB.txt");
int i = 0;
while (i < 1800)
{
    string[] loadedData = loadNewData.ReadLine().Split(';');
    dataList[i] = loadedData;
    i++;
}

As you are splitting loadedNewData, you receive string[] already, because Split() function returns string[].
