C#將值從表格1傳遞到表格2

[英]C# Pass values from form 1 to form 2

我的Winforms應用程序中有2個不同的Form元素。 現在,我嘗試通過運行以下代碼將一些變量從表格1傳遞到表格2:

async void bunifuFlatButton2_Click(object sender, EventArgs e)
{

    if (string.IsNullOrWhiteSpace(bunifuMaterialTextbox2.Text))
    {
        MessageBox.Show("Please get the authentification Pin before continuing.", "Twitter Buddy error");
    }
    else
    {
        await pinAuth.CompleteAuthorizeAsync(bunifuMaterialTextbox2.Text);
        SharedState.Authorizer = pinAuth;

        var credentials = pinAuth.CredentialStore;

        if (credentials != null)
        {
            string oauthToken = credentials.OAuthToken;
            string oauthTokenSecret = credentials.OAuthTokenSecret;
            string screenName = credentials.ScreenName;
            ulong userID = credentials.UserID;

            new Form1(oauthToken, oauthTokenSecret, screenName, userID).Show();
            this.Hide();
        }
        else
        {
            MessageBox.Show("Please authorize this application before continuing.", "Twitter Buddy error");
        }
    }
}

現在,我正在嘗試接受第二種形式的值,如下所示:

public Form1(string oauthToken, string oauthTokenSecret, string screenName, ulong userID)
{
    string OauthToken = oauthToken;
    string OauthTokenSecret = oauthTokenSecret;
    string ScreenName = screenName;
    ulong UserID = userID;

    InitializeComponent();
}

但是不知何故,Form 2不允許我使用這些值。 正在測試以下內容:

MessageBox.Show(this.OauthToken);

並收到以下錯誤消息:

Error CS1061 'Form1' does not contain a definition for 'OauthToken' and no extension method 'OauthToken' accepting a first argument of type 'Form1' could be found (are you missing a using directive or an assembly reference?)

有人知道我在做什么錯嗎?

將變量的聲明移出。 現在,變量的范圍僅限於構造函數。 在MSDN上閱讀有關變量范圍的更多信息。

string OauthToken;
string OauthTokenSecret;
string ScreenName;
ulong UserID;

public Form1(string oauthToken, string oauthTokenSecret, string screenName, ulong userID)
{
    this.OauthToken = oauthToken;
    this.OauthTokenSecret = oauthTokenSecret;
    this.ScreenName = screenName;
    this.UserID = userID;

    InitializeComponent();
}
