获取"索引超出数组的范围"异常

Question

我们有一个数据表"st",有两列"word"和"binary"

void replace()
    {

        string s1="", s2="";            
        StreamReader streamReader;
        streamReader = File.OpenText("C:\\text.txt");
        StreamWriter streamWriter = File.CreateText("C:\\sample1.txt");
        int x = st.Rows.Count;
       // int i1 = 0;                                       
            // Now, read the entire file into a string
            while ((line = streamReader.ReadLine()) != null)
            {
                for (int i = 0; i < x; i++)
                {

                s1 = Convert.ToString(st.Rows[i]["Word"]);
                s2 = Convert.ToString(st.Rows[i]["Binary"]);
                s2+="000";
                char[] delimiterChars = { ' ', '\t' };
                String[] words = line.Split(delimiterChars);

                    // Write the modification into the same file                    
                String ab = words[i]; //exception occurs here
                // Console.WriteLine(ab);
                streamWriter.Write(ab.Replace(s1,s2));                                 
                }                
            }
        streamReader.Close();
        streamWriter.Close();
    }

我们得到的"索引超出了数组的范围"异常.我们无法找到问题.提前致谢

编辑:tnx给所有帮助过的人.我做了这个,它以某种方式工作:

 void replace()
    {
        string s1 = "", s2 = "";
        StreamReader streamReader;
        streamReader = File.OpenText("C:\\sample1.txt");
        StreamWriter streamWriter = File.CreateText("C:\\sample1.txt");
        int x = st.Rows.Count;           
        while ((line = streamReader.ReadLine()) != null)
        {
            char[] delimiterChars = { ' ', '\t' };
            String[] words = line.Split(delimiterChars);
            foreach (string str in words)
            {

                s1 = str;
                DataRow drow = st.Rows.Find(str);
                if (drow != null)
                {
                    index = st.Rows.IndexOf(drow);
                    s2 = Convert.ToString(st.Rows[index]["Binary"]);
                  // s2 += "000";
                    // ab = words[i];                        
                    Console.WriteLine(s1);
                    Console.WriteLine(s2);
                    streamWriter.Write(str.Replace(s1, s2));                                 
                }
                else
                    break;
            }               
        }
        streamReader.Close();
        streamWriter.Close();
    }

tnx再一次给大家.问候,萨加尔

你基于i的方式是行数,即X,而不是字符串数组的长度.因此,您可能有100行,但字符串只分为5个字符串值.
