excelFilesNames is a array of string and there is more than 1 value in excelFilesNames.
While printing oVariableName[2] value it prints "system.string". i want to print all values of excelFilesNames by assigning it to oVariableName[2].
the code is below
Object[] oVariableName = new object[3];
oVariableName[2] = excelFilesNames;
MessageBox.Show(oVariableName[2].ToString());
Object[] oVariableName = new object[3];
oVariableName[2] = string.Join(",", excelFilesNames);
MessageBox.Show(oVariableName[2]);
You don't need to use a Object[] though:
var fileNames = string.Join(",", excelFilesNames);
MessageBox.Show(fileNames);
If excelFilesNames is an array of strings, iterate it with a foreach:
Object[] oVariableName = new object[3];
oVariableName[2] = excelFilesNames;
foreach (string s in oVariableName[2])
{
MessageBox.Show(s);
}
Note I'm not sure why you assign the string[] to an object field inside an object[], but I'll assume for your question that it's whats needed to be done.
Since the contents of oVariableName[2] is known to be a string[], you can cast it to string[] and make use of string.Join() to create a multiline string with one line per filename, like so:
MessageBox.Show(string.Join("\n", (string[])oVariableName[2]));
However this will explode at runtime if oVariableName[2] is not an array of strings. You could protect against like that:
var asStringArray = oVariableName[2] as string[];
if (asStringArray != null)
MessageBox.Show(string.Join("\n", asStringArray));
I don't really understand why you're using an array of objects in this way, but I guess there's some background that you haven't told us about.
excelfileNames is array of string, so when your assigning to the oVariableName[2] you should assign a specific value of it, rather assigning the whole object.
something like below code.
string [] excelFilesNames = new string[]{ "One","Two"};
Object[] oVariableName = new object[3];
oVariableName[2] = excelFilesNames[1];
MessageBox.Show(oVariableName[2].ToString());
MessageBox.Show(excelFilesNames[2]);?
