Hi,

I'm trying to create a webservice and I've looked at all different tutorials but I just can't seem to grasp it. Can someone help me? This is what I'm trying to do;

Create a Webservice that allows the user to enter SMS-style abbreviations, and returns the expanded meaning. Populated from a comma separated text file containing SMS-style abbreviations, and their expanded meaning

use a Dictionary Class to hold a list of SMS abbreviations and their meanings in English

Create an application that consumes the webservice.

I have some code but I'm unsure how to import/use it in a webservice. This is the code I currently have;

      private string dirCSV;
        private string fileNevCSV;
        public string FileNevCSV
        {
            get { return fileNevCSV; }
            set { fileNevCSV = value; }
        }
        public string dirCSV
        {
            get { return dirCSV; }
            set { dirCSV = value; }
        }

        
        public DataSet loadCVS(int noofrows)
        {
            DataSet ds = new DataSet();
            try
            {
                
                string strConnString = "Driver={Microsoft Text Driver (*.txt; *.csv)};Dbq=" + this.dirCSV.Trim() +
";Extensions=asc,csv,tab,txt;Persist Security Info=False";
                string sql_select;
                OdbcConnection conn;
                conn = new OdbcConnection(strConnString.Trim());
                conn.Open();
  
                
                if (noofrows == -1)
                {
                    sql_select = "select * from [" + this.FileNevCSV.Trim() + "]";
                }
                else
                {
                    sql_select = "select top " + noofrows + " * from [" + this.FileNevCSV.Trim() + "]";
                }
               
                OdbcDataAdapter obj_oledb_da = new OdbcDataAdapter(sql_select, conn);
  
                
                obj_oledb_da.Fill(ds, "csv");
  
                /
                conn.Close();
            }
            catch (Exception e) //Error
            {
            }
            return ds;
         }
 
this.dirCSV = "file path";
            this.fileNevCSV ="file name";
            DataSet ds = loadCVS(-1);
            DataTable table = ds.Tables[0];
            foreach (DataRow row in table.Rows)

任何人都可以帮我创建吗？或者指出一个好的方向？

Can anyone help me create this? Or point me in the direction of a good source?

推荐答案

我真的看不出你的问题所在。这听起来像一个简单的Web服务，只有一个WebMethod接受一个字符串并返回一个字符串。如果您在创建WebService时遇到问题，我建议您从这个很好的教程开始：您的第一个C＃网络服务 [ ^ ]



PS：我看，这是你的作业，所以挣扎一下，如果你卡住了就来这里更具体的一步。

I really cant't see where your problem is. This sounds like a simple web service with a single WebMethod accepting a string and returning a string. If you have trouble creating a WebService, I suggest you start with this nice tutorial: Your first C# Web Service[^]

PS: as I see, this is your homework, so struggle a little bit, and come here if you stuck at a more concrete step.
