Question

我使用下面的代码，当我在代码下面运行时，一半的文本只显示在标签框中。我想在标签框文字中显示全行？怎么做？

Label dynamiclabel1 = new Label();
dynamiclabel1.Location = new Point(280, 90);
dynamiclabel1.Name = "lblid";
dynamiclabel1.Size = new Size(150, 14);    
dynamiclabel1.Text="Smith had omitted the paragraph in question (an omission which had escaped notice for twenty years) on the ground that it was unnecessary and misplaced; but Magee suspected him of having been influenced by deeper reasons.";        
dynamiclabel1.AutoSize = true;
dynamiclabel1.Font = new Font("Arial", 10, FontStyle.Regular);
panel1.Controls.Add(dynamiclabel1);

Answer 1

您已同时使用dynamiclabel1.AutoSize = false;和显式标签尺寸设置，这没有任何意义。

如果要在标签文字中启用自动换行功能，则必须先设置Height，然后再设置{{1}}。目前它只有14个像素的高度，因此不可能使文本多行。将它增加到约200像素，所有文本将放在标签内几行。

            Label dynamiclabel = new Label();
            dynamiclabel.Location = new Point(38, 30);
            dynamiclabel.Name = "lbl_ques";
            dynamiclabel.Text = question;
            //dynamiclabel.AutoSize = true;
            dynamiclabel.Size = new System.Drawing.Size(900, 26);
            dynamiclabel.Font = new Font("Arial", 9, FontStyle.Regular);

Answer 3

如果增加高度并想要更少的行，请将Width属性设置为更大的值;

如果要根据字体/文字大小选择行数，可以执行以下操作：

Label dynamiclabel1 = new Label();
dynamiclabel1.Location = new Point(280, 90);
dynamiclabel1.Name = "lblid";
dynamiclabel1.Size = new Size(150, 100);
dynamiclabel1.Text = "Smith had omitted the paragraph in question (an omission which had escaped notice for twenty years) on the ground that it was unnecessary and misplaced; but Magee suspected him of having been influenced by deeper reasons.";

dynamiclabel1.Font = new Font("Arial", 10, FontStyle.Regular);
int lines = 3; //number of lines you want your text to display in
using (Graphics g = CreateGraphics())
{
     SizeF size = g.MeasureString(dynamiclabel1.Text, dynamiclabel1.Font);
     float w=size.Width / lines;
     dynamiclabel1.Height = (int)Math.Ceiling(size.Height*lines);
     dynamiclabel1.Width = (int)Math.Ceiling(w);
}
panel1.Controls.Add(dynamiclabel1);

修改
如果您知道的是您所拥有的宽度，并且您希望标签调整高度以显示所有内容，则可以执行以下操作：

Label dynamiclabel1 = new Label(); dynamiclabel1.Location = new Point(280, 90); dynamiclabel1.Name = "lblid"; dynamiclabel1.Size = new Size(150, 100); dynamiclabel1.Text = "Smith had omitted the paragraph in question (an omission which had escaped notice for twenty years) on the ground that it was unnecessary and misplaced; but Magee suspected him of having been influenced by deeper reasons."; dynamiclabel1.Font = new Font("Arial", 10, FontStyle.Regular); int width = 600; //Width available to your label using (Graphics g = CreateGraphics()) { SizeF size = g.MeasureString(dynamiclabel1.Text, dynamiclabel1.Font); lines = (int)Math.Ceiling(size.Width / width); dynamiclabel1.Height = (int)Math.Ceiling(size.Height * lines); dynamiclabel1.Width = width; } panel1.Controls.Add(dynamiclabel1);
