我正在编写简单的编译器而不使用语法生成器。 Here 。我编写了读取file.txt的扫描代码，并将其分类为Identifier或Revers单词，Number，Variable ..等。 我得到了我想要的结果但是可以用这个代码来完成我的意思是应用语法分析吗？和解析？ 。因为我尝试用java编写，我用错误的方式编写它。我想看看我做得对，特别是我不擅长C＃codding。
阵列：
string[] Rw = new string[8];
Rw[0] = "for";
Rw[1] = "while";
Rw[2] = "end";
Rw[3] = "contiune";
Rw[4] = "if";
Rw[5] = "break";
Rw[6] = "do";
Rw[7] = "return";
string[] id = new string[6];
id[0] = "int";
id[1] = "float";
id[2] = "string";
id[3] = "double";
id[4] = "bool";
id[5] = "char";
string[] op = new string[6];
op[0] = "+";
op[1] = "-";
op[2] = "/";
op[3] = "*";
op[4] = "%";
string[] Num = new string[10];
Num[0] = "0";
Num[1] = "1";
Num[2] = "2";
Num[3] = "3";
Num[4] = "4";
Num[5] = "5";
Num[6] = "6";
Num[7] = "7";
Num[8] = "8";
Num[9] = "9";
string[] var = new string[17];
var[0] = "a";
var[1] = "b";
var[2] = "A";
var[3] = "B";
var[4] = "C";
var[5] = "d";
var[6] = "D";
var[7] = "X";
var[8] = "x";
var[9] = "Y";
var[10] = "y";
var[11] = "z";
var[12] = "Z";
var[13] = "v";
var[14] = "V";
var[15] = "f";
var[16] = "F";
阅读和分裂：
char[] delimiterChars = { ' ', ',', '.', ':', '\t' };
using (System.IO.StreamReader file = new System.IO.StreamReader(@"C:\Users\caza\Desktop\1.txt"))
{
while ((line = file.ReadLine()) != null)
{
string[] token = line.Split(delimiterChars);
foreach (string s in token)
{
// Console.WriteLine(s);
foreach (string z in Rw)
{
if (s == z)
{
Console.WriteLine(s + " is a Reserved Word ");
}
}
foreach (string y in id)
{
if (s == y)
{
Console.WriteLine(s + " is a identifier ");
}
}
foreach (string o in op)
{
if (s == o)
{
Console.WriteLine(s + " is a Operation ");
}
}
foreach (string n in Num)
{
if (s == n)
{
Console.WriteLine(s + " is a Number ");
}
}
foreach (string v in var)
{
if (s == v)
{
Console.WriteLine(s + " is a Variable");
}
}
}
}
}
Console.WriteLine("Press any key to exit.");
Console.ReadKey();
}
