如何在c#本地报表(rdlc- WinForms)中动态设置字体大小以适应文本框大小？

   Microsoft.Reporting.WinForms.LocalReport report = (Microsoft.Reporting.WinForms.LocalReport)sender;

   foreach (Microsoft.Reporting.WinForms.ReportItem item in report.GetChildren())

   {

       if (item.GetType() == typeof(Microsoft.Reporting.WinForms.TextBox))

       {

           Microsoft.Reporting.WinForms.TextBox textBox = (Microsoft.Reporting.WinForms.TextBox)item;

           // 在这里根据文本框的大小动态调整字体大小

           AdjustFontSize(textBox);

       }

   }

   float fontSize = textBox.FontSize;

   float textBoxWidth = textBox.Width;

   float textBoxHeight = textBox.Height;

   float textWidth = TextRenderer.MeasureText(textBox.Text, textBox.Font).Width;

   float textHeight = TextRenderer.MeasureText(textBox.Text, textBox.Font).Height;

   if (textWidth > textBoxWidth || textHeight > textBoxHeight)

   {

       while (textWidth > textBoxWidth || textHeight > textBoxHeight)

       {

           fontSize -= 0.5f;

           textBox.FontSize = fontSize;

           textWidth = TextRenderer.MeasureText(textBox.Text, textBox.Font).Width;

           textHeight = TextRenderer.MeasureText(textBox.Text, textBox.Font).Height;

       }

   }
