這幾天一直在弄128條碼的事情，找了相關的資料，也沒找到。后來沒辦法只能改成code39的條碼。現在把它寫出來，與大家分享
1.先下載一種免費的 code39條碼字體
2.建個類 為 code39 并寫入以下代碼
代碼如下:
public sealed class Code39
{
#region private variables
/// <summary>
/// The Space Between each of Title, BarCode, BarCodeString
/// </summary>
private const int SPACE_HEIGHT = 3;
SizeF _sizeLabel = SizeF.Empty;
SizeF _sizeBarCodeValue = SizeF.Empty;
SizeF _sizeBarCodeString = SizeF.Empty;
#endregion
#region Label
private string _label = null;
private Font _labelFont = null;
/// <summary>
/// BarCode Title (條碼標簽)
/// </summary>
public string Label
{
set { _label = value; }
}
/// <summary>
/// BarCode Title Font (條碼標簽使用的字體)
/// </summary>
public Font LabelFont
{
get
{
if (_labelFont == null)
return new Font("Arial", 10);
return _labelFont;
}
set { _labelFont = value; }
}
#endregion
private string _additionalInfo = null;
private Font _addtionalInfoFont = null;
/// <summary>
/// Additional Info Font (附加信息字體)
/// </summary>
public Font AdditionalInfoFont
{
set { _addtionalInfoFont = value; }
get
{
if (_addtionalInfoFont == null) return new Font("Arial", 10);
return _addtionalInfoFont;
}
}
/// <summary>
/// Additional Info Content, if "ShowBarCodeValue" is true, the info is unvisible
/// 附加信息，如果設置ShowBarCodeValue為true,則此項不顯示
/// </summary>
public string AdditionalInfo
{
set { _additionalInfo = value; }
}
#region BarCode Value and Font
private string _barCodeValue = null;
/// <summary>
/// BarCode Value (條碼值)
/// </summary>
public string BarCodeValue
{
get
{
if (string.IsNullOrEmpty(_barCodeValue))
throw new NullReferenceException("The BarCodeValue has not been set yet!");
return _barCodeValue;
}
set { _barCodeValue = value.StartsWith("*") && value.EndsWith("*") ? value : "*" + value + "*"; }
}
private bool _showBarCodeValue = false;
/// <summary>
/// whether to show the original string of barcode value bellow the barcode
/// 是否在條碼下方顯示條碼值，默認為false
/// </summary>
public bool ShowBarCodeValue
{
set { _showBarCodeValue = value; }
}
private Font _barCodeValueFont = null;
/// <summary>
/// the font of the codestring to show
/// 條碼下方顯示的條碼值的字體
/// </summary>
public Font BarCodeValueFont
{
get
{
if (_barCodeValueFont == null)
return new Font("Arial", 10);
return _barCodeValueFont;
}
set { _barCodeValueFont = value; }
}
private int _barCodeFontSize = 50;
