如何使用从Form1到Form2的代码继承按钮

Question

I have a main form which is called form and a second form called form2 . Form contains a button with a coded function inside. Now on my form2 I have the same button which performs the same function on form or which I want it to perform the same function as form1.

On form2 I have created a button of which I want it to use the same function from the form1 . Now I want to be able to click the button from form2 and it calls the button funtion from form1.

I have done this but I don't know how I can make it work

Form1 (mainform)

    public Button newButton
    {
        get
        {
            return btnNewfile;
        }
    }
    public void SetLanguage(string cbolang)
    {
        cboLanguage.SelectedValue = cbolang;
    }

Form2

    public frmMain_Page _frmMainform;

    public FrmLanguage(frmMain_Page _frmMainform)
    {
        InitializeComponent();
        this._frmMainform = _frmMainform;
    }

    public frmMain_Page _Main
    {
        get;
        set;
    }

    //from this button I can't get the main button from the main form
    private void btnCreatFile_Click(object sender, EventArgs e)
    {
        _frmMainform.newButton.btnNewfile; 

       //Error  19  'System.Windows.Forms.Button' does not contain a definition for 'btnNewfile' and no extension method 'btnNewfile' accepting a first argument of type 'System.Windows.Forms.Button' could be found (are you missing a using directive or an assembly reference?)


    }

this is the button with coded function. am trying to take it from this button

    private void btnNewfile_Click(object sender, EventArgs e)
    {
        _frmMainform.newButton;

        XmlDocument _doc = new XmlDocument();

        FileInfo _fileInfo = new FileInfo(txtInputfile.Text);
        _InputFileName = _fileInfo.Name;
        _InputFileSourceDirectory = _fileInfo.DirectoryName;
        _InputFileExternsion = _fileInfo.Extension;

        _OutFileName = cboLanguage.SelectedItem.ToString() + "-language.resx";

        string outputFilePath = txtInputfile.Text.Replace(_InputFileName, _OutFileName);
        File.Copy(txtInputfile.Text, outputFilePath);
        string text = File.ReadAllText(outputFilePath);

        XDocument doc = XDocument.Load(outputFilePath);
        foreach (var valueNode in doc.Descendants("data").SelectMany(n => n.Elements("value")))
        {
            valueNode.Value = string.Empty;
        }
        foreach (var commentNode in doc.Descendants("data").SelectMany(n => n.Elements("comment")))
        {
            commentNode.Value = DeleteBetween(commentNode.Value, "Font");
            commentNode.Value = DeleteBetween(commentNode.Value, "DateStamp");
            commentNode.Value = DeleteBetween(commentNode.Value, "Comment");
        }
        doc.Save(outputFilePath);
        txtOutputfile.Text = _InputFileSourceDirectory + "\\" + _OutFileName;


        _doc.Load(outputFilePath);
        string xmlcontents = _doc.InnerXml;
        //lblversion.Text = updateversion.ToString();
    }

Answer 1

private void btnCreatFile_Click(object sender, EventArgs e)
{
    // because newButton returns btnNewfile
    // You can access btnNewLife by : _frmMainform.newButton
    _frmMainform.newButton.Text = "My Button";
}

Also your newButton returns a Button object. A Button object dose not have a child Button. So you just need to access newButton to get btnNewLife.
