How to use created Instance on all forms / How to make my instance public C# windowsforms

Hello it is probably easy question for you, I'm a beginner and I'm making my own simple game and I want to use a Class:Gamer, which I want to initialize in MainWindow(Form1.cs) from a save file. From then, I want to use it on another Forms aswell, but somehow I can't make the instance go public.
Could you tell me what I'm doing wrong? Or is there another way how to solve this?
Thank you :)
Code on Form1:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Drawing.Text;
using System.IO;
namespace THE_GAME
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
public static Gamer Player;
private void MainWindow_Load(object sender, EventArgs e)
{
//load from savefile lvl;hp;money;gun;armor,name
string allData = File.ReadAllText("../../saveFile/save.txt");
string[] dataFromSave = new string[5];
dataFromSave = allData.Split(';');
Player = new Gamer(dataFromSave[0], dataFromSave[1], dataFromSave[2], dataFromSave[3], dataFromSave[4], dataFromSave[5]);
}
}
}
Code on secondForm2:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Drawing.Text;
namespace THE_GAME
{
public partial class Statistics : Form1
{
public Statistics()
{
InitializeComponent();
}
private void Statistics_Load(object sender, EventArgs e)
{
//labels stats
labelName.Text = Form1.Player.GetName();
labelHealth.Text = Form1.Player.GetHealth().ToString();
labelMoney.Text = Form1.Player.GetMoney().ToString();
}
private void buttonBack_Click(object sender, EventArgs e)
{
MainMenu menu = new MainMenu();
menu.Show();
this.Close();
}
}
}
Thank you for your time.

To get at the Gamers Player object from a different Form just do
Form1.Player;
ie
var nam = Form1.Player.Name;
Form1.Player.Die();
etc
PS As I said in a comment - its extremely odd to dereive a form of yours from another one of your forms. Like this
public partial class Statistics : Form1

{
InitializeComponent();
_total = total; _cashr = cashr; _cashc = cashc;
_data = data;
}
private void ProductsReceipt_Load(object sender, EventArgs e)
{
DataReceiptBindingSource.DataSource = _data;
Microsoft.Reporting.WinForms.ReportParameter[] param = new
Microsoft.Reporting.WinForms.ReportParameter[]

new Microsoft.Reporting.WinForms.ReportParameter("ptotal",
_total),
new Microsoft.Reporting.WinForms.ReportParameter("pcashr",
_cashr),
new Microsoft.Reporting.WinForms.ReportParameter("pcashc",
_cashc),
new Microsoft.Reporting.WinForms.ReportParameter

};
this.rptProductsReceipt.LocalReport.SetParameters(param);
this.rptProductsReceipt.RefreshReport();
this.rptProductsReceipt.ZoomMode =
Microsoft.Reporting.WinForms.ZoomMode.PageWidth;
}
private void btnReports_Click(object sender, EventArgs e)
{
rptProductsReceipt.PrintDialog();
}
}
}

i never use your method but i use this
rptProductsReceipt.PrintToPrinter(1, false, 0, 0);
after using adapter and data table

How do I get a string from a TextBox in VS and then compare it to an integer using an if statement?

Alright, I'm pretty new to C# and I'm trying to figure out how I could grab a string or a number from my TextBox in Visual Studio(Windows Form Application) and then figure out if that string is 0.
I've tried doing
if(Calculations.Text == 0)
{
Calculations.Text = 1
}
but to my avail it did not work.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WindowsFormsApp1
{
public partial class Calculatrice : Form
{
public Calculatrice()
{
InitializeComponent();
}
private void One_Click(object sender, EventArgs e)
{
if(Calculations.Text)
{
}
}
private void Calculatrice_Load(object sender, EventArgs e)
{
}
}
}
This is all I have right now I'm pretty stuck.
I want to be able to use the if statement to make comparisons with int values.

You should enclose your string in quotes before using them
if(Calculations.Text.Trim () == "0")
{
Calculations.Text = "1";
}

//Example:if Calculations is your textbox id,then
string input = calculations.text.tostring();
//then compare zero with " "
if(input == "0")
{
calculations.text= 1;
}

A user can put anything in a TextBox. Use TryParse which will provide a zero even if it fails (returns false)
private void OPCode()
{
int.TryParse(Calculations.Text, out int i);
if (i == 0)
{
Calculations.Text = 1.ToString();
}
}

How do I make my DataGridView read info of a text file C#

so my issue is that, I can´t make my DataGridView read information from a text file already created, don´t know what to do really, I am kinda new to C#, so I hope you can help me :D
Here is my code to save the values from my grid:
private void buttonGuardar_Click(object sender, EventArgs e)
{
string[] conteudo = new string[dataGridView1.RowCount * dataGridView1.ColumnCount];
int cont = 0;
foreach (DataGridViewRow row in dataGridView1.Rows)
{
foreach (DataGridViewCell cell in row.Cells)
{
conteudo[cont++] = cell.Value.ToString();
}
}
File.WriteAllLines("dados.txt", conteudo);
And now, from a different form, there is another Grid that must be fill with the values saved in that File
The present code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.IO;
namespace WindowsFormsApplication31
{
public partial class Form3 : Form
{
DateTime start, end;
private void Form3_Load(object sender, EventArgs e)
{
textBox1.Text = start.ToString("dd-MM-yyyy");
textBox2.Text = end.ToString("dd-MM-yyyy");
}
public Form3(DateTime s, DateTime e)
{
InitializeComponent();
start = s;
end = e;
}
}
}
In conclusion, both of the grid should have 4 Cells:
0-Designação
1-Grupo
2-Valor
3-Data
And the second one from Form3, should read the text file, in the right order
Hope you can help me, Thanks.

Please try this below.
I have exported the grid data in to a text file as same structure as how it appears in grid as below.
private void button1_Click(object sender, EventArgs e)
{
TextWriter writer = new StreamWriter("Text.txt");
for (int i = 0; i < DataGridView1.Rows.Count; i++)
{
for (int j = 0; j < DataGridView1.Columns.Count; j++)
{
writer.Write(DataGridView1.Rows[i].Cells[j].Value.ToString() + "\t");
}
writer.WriteLine("");
}
writer.Close();
}
Created a new class with properties as the column names and a method to load the exported data into a list collection of class as shown below.Here in this example ,my grid has two columns Name and Marks.so i declared those two properties in my user class
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
namespace WindowsFormsApplication1
{
public class User
{
public string Name { get; set; }
public string Marks { get; set; }
public static List<User> LoadUserListFromFile(string path)
{
var users = new List<User>();
foreach (var line in File.ReadAllLines(path))
{
var columns = line.Split('\t');
users.Add(new User
{
Name = columns[0],
Marks = columns[1]
});
}
return users;
}
}}
Now on the form load event of second form,call the above method and bind to the second grid as shown below
private void Form2_Load(object sender, EventArgs e)
{
dataGridView2.DataSource = User.LoadUserListFromFile("Text.txt");
}
Pleas mark this as answer,if it helps.

C# - Tier Separation - How to use these delegates?

Here's the relevant code:
ClickMeGame.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ClassLibrary
{
public class ClickMeGame
{
public OnClickMe onClickMeCallback;
public int score;
public ClickMeGame()
{
score = 0;
}
private void IncrementScore()
{
score++;
}
}
}
ClickMeCallBackDefinitions.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ClassLibrary
{
public delegate void OnClickMe();
}
MainWindow.cs (Windows Form)
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using ClassLibrary;
namespace ClickMe
{
public partial class mainWindow : Form
{
private ClickMeGame game;
public mainWindow()
{
InitializeComponent();
game = new ClickMeGame();
game.onClickMeCallback = clickMeButton_Click();
}
private void clickMeButton_Click(object sender, EventArgs e)
{
UpdateUI();
}
private void UpdateUI()
{
scoreLabel.Text = string.Format("The score is: {0}", game.score);
}
}
}
So what I'm trying to do is, when the user clicks a button present on the form, I want a label on the form to update with the game score which increments with every click.
I'm learning about/want to be able to do this with delegates in that I want to separate the project into 2 tiers; Presenation and Logic. I know it's unnecessary to do so, but I'd like to make it such that when you click the button, the Windows Form receives information about the game score via delegates/callback methods. I'm unsure how to do this, but I tried making the callback definition and referencing it, but I'm lost from there.

Assuming that the UI button uses the click event clickMeButton_Click then here you go.
public partial class mainWindow : Form
{
private ClickMeGame game;
public mainWindow()
{
InitializeComponent();
game = new ClickMeGame();
game.onClickMeCallback = param => UpdateUI();
}
private void clickMeButton_Click(object sender, EventArgs e)
{
game.onClickMeCallback.Invoke();
}
private void UpdateUI()
{
scoreLabel.Text = string.Format("The score is: {0}", game.score);
}
}
