1、解析文件头，字段名部分如果有中文命名字段会出错
在DbfHeader类的Read(BinaryReader reader)方法
//char[] buffer = new char[11];
//buffer = reader.ReadChars(11);
//string sFieldName = new string(buffer);
//yang：ReadChars(11)读取中文字段名时会出错，已改为ReadBytes(11)//Encoding注意UTF-8与GBK
byte[] bytes = reader.ReadBytes();
string sFieldName = Encoding.Default.GetString(bytes);
int nullPoint = sFieldName.IndexOf((char));
if (nullPoint != -)
sFieldName = sFieldName.Substring(, nullPoint);
2、在DbfColumn类，没有设定字段类型可能存在的Float
public enum DbfColumnType
{ /// <summary>
/// Character less than 254 length
/// ASCII text less than 254 characters long in dBASE.
///
/// Character fields can be up to 32 KB long (in Clipper and FoxPro) using decimal
/// count as high byte in field length. It's possible to use up to 64KB long fields
/// by reading length as unsigned.
///
/// </summary>

/// Number Length: less than 18
/// ASCII text up till 18 characters long (include sign and decimal point).

/// </summary>
