我遇到了最奇怪的问题,我不得不遗漏一些东西.
这是导致错误的代码.
if (radLot.Checked == true)
{
SymbolSpecification = "LotRenderer";
}
if (radWaterMeter.Checked == true)
{
SymbolSpecification = "WaterMeterRenderer";
}

正如你所看到的,我甚至不使用= +或 - = ...我实际上在我的代码中没有它...任何帮助将不胜感激.
我正在编写一个简单的程序,从文件中读取莫尔斯代码并将其转换为纯文本.我虽然得到了一些疯狂的错误.我对perl不太熟悉,我不得不从命令行运行它.以下是我收到的错误和代码.我可能错误地运行了它.我在命令行输入:"perl -w Lott_Morse.pl morse.txt".任何帮助,将不胜感激.

C#:
private List<string> dataList;
private int ShowAuditLogForPrimaryID { get; set; }
private string xmlString;
private DataSet _dataSet;
SqlDataReader reader = sqlCommand.ExecuteReader();
dataList = new List<String>();
while (reader.Read())

for (int i = 0; i < reader.FieldCount; i++)
{
string rdr = reader[i].ToString();
dataList.Add(rdr);
string Name = reader.GetName(i);
xmlString = xmlString + Name + "=" + " " + "\"" + dataList[i].ToString() + "\"" + " ";
Console.WriteLine(xmlString);

它包括字符串中的反斜杠,它不允许我的xml阅读器能够读取它.
我感谢任何帮助.提前致谢!
