well, as said - your field initializers cant access the members they are trying to you need to move that code to the constructor

huh

Pobiega•5mo ago

initializers are limited in what they can do. they cant access other non-static members, since those might not have been initialized yet its a chicken and egg type thing so you need to initialize them inside your constructor instead

ILikeCats!OP•5mo ago

so define them as what they are?

Pobiega•5mo ago

yes, feel free to define them there but give them their value in the ctor

ILikeCats!OP•5mo ago

so first define like XLWorkbook (varname); then XLWorkbook (varname) = ("BLEH")

something like that, yeah

using ClosedXML.Excel;

namespace excelbetter;

public partial class Form1 : Form
{
    private const string savepath2 = @"C:\Users\nuh uh\excel\YIPPE.xlsx";
    private XLWorkbook _workingFile;
    private IXLWorksheet _spreadsheet1;

    public Form1()
    {
        _workingFile = new XLWorkbook(savepath2);
        _spreadsheet1 = _workingFile.AddWorksheet("s");
        
        InitializeComponent();
    }

    public void process_Data_Click(object sender, EventArgs e)
    {
        Close();
    }
}

using ClosedXML.Excel;

namespace excelbetter;

public partial class Form1 : Form
{
    private const string savepath2 = @"C:\Users\nuh uh\excel\YIPPE.xlsx";
    private XLWorkbook _workingFile;
    private IXLWorksheet _spreadsheet1;

    public Form1()
    {
        _workingFile = new XLWorkbook(savepath2);
        _spreadsheet1 = _workingFile.AddWorksheet("s");
        
        InitializeComponent();
    }

    public void process_Data_Click(object sender, EventArgs e)
    {
        Close();
    }
}
