c# - 为什么我的标签没有显示所有文本？

Question

public int dialog()
{
    Form prompt = new Form(); // creates form

    //dimensions
    prompt.Width = 300;
    prompt.Height = 125;

    prompt.Text = "Adding Rows"; // title

    Label amountLabel = new Label() { Left = 50, Top = 0, Text = "Enter a number from 1-50" }; // label for prompt
    amountLabel.Font = new Font("Microsoft Sans Serif", 9.75F);
    TextBox value = new TextBox() { Left = 50, Top = 25, Width = prompt.Width / 2 }; // text box for prompt
    Button confirmation = new Button() { Text = "Ok", Left = prompt.Width / 2 - 50, Width = 50, Top = 50 }; // ok button
    confirmation.Click += (sender, e) => { prompt.Close(); }; // if clicked it will close

    prompt.AcceptButton = confirmation; // enter

    prompt.KeyPreview = true;
    prompt.KeyDown += (sender, e) =>
    {
        if (e.KeyCode == Keys.Escape) prompt.DialogResult = DialogResult.Cancel; // user presses ESC key to close
    };

    // adding the controls
    prompt.Controls.Add(value);
    prompt.Controls.Add(confirmation);
    prompt.Controls.Add(amountLabel);
    prompt.ShowDialog();

    // returning and checking if int block
    int num;
    Int32.TryParse(value.Text, out num);
    return num;
}

这是完整的代码。代码的简短版本是:

Label amountLabel = new Label() { Left = 50, Top = 0, Text = "Enter a number from 1-50" };
prompt.Controls.Add(amountLabel);

问题是它只会显示“输入数字”。由于某种原因，它不会显示全文。我尝试了更短的“E”并且它起作用了。我什至尝试了“输入数字来自”，但它仍然没有完全显示。

您可以启用 AutoSize，如果您通过设计器创建它，它默认设置为 true:

Label amountLabel
    = new Label { AutoSize = true, Left = 50, Top = 0, Text = "Enter a number from 1-50" };
