由于条形码扫描器被认为是一个键盘，我发现捕捉按键事件，使我填写一个字符列表。

List<char> charList = new List<char>();
private void textEditCode_KeyPress(object sender, KeyPressEventArgs e)
{
  charList.Add(e.KeyChar);
}
string datamatrix = new string(charList.ToArray()); //charList is filled      by pressing the keys, or when receiving data from the scanner
Aii = gS1.Parse(datamatrix); // Aii = new Dictionary<string, string>();

字符串
之后，我将字符列表解析为GS1内容，并可以调用NMVS服务：

string Batch = gS1.GetValue(EGS1AI.Batch);
string ProductCode = gS1.GetValue(EGS1AI.GTIN);
System.DateTime ExpDate = gS1.GetValue(EGS1AI.ExpirationDate);
string SerialNumber = gS1.GetValue(EGS1AI.SerialNumber);
string dat = ExpDate.ToString("yyMMdd");
Log log = new Log(App.LogFolder(), App.AppName);
G110Response response = G110.G110Verify(ProductCode, Batch, dat, 
SerialNumber, log);

型
然后处理响应
