用数据表值替换文件中的文本

我们有一个示例文本文件，其中包含文本：

上帝为爱他的人准备的东西

我们将文本读取到数据表中，并分配一些值，如下所示：

 The            1
----------
 things         2
----------
 God            3
----------
 has            4
----------
 prepared       5
----------
 for            6
----------
 those          7
----------
 who            8
----------
 love           9
----------
 him            10
----------

我们正在尝试用这些相应的数字替换输入文件中的文本。有可能吗？如果可能的话，我们该怎么做？

第2版：我们这样编辑代码：

:

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[i1]; // exception occurs here
                   // Console.WriteLine(ab);
                    streamWriter.Write(ab.Replace(s1, s2));
                    i1++;                                       
                }                
            }
        streamReader.Close();
        streamWriter.Close();
    }

但是我们得到了一个"数组索引越界"的异常。我们找不到问题。提前感谢
