C# 将DataTable存储到DBF文件中

（准备）生成一个DataTable

 /// <summary>
 /// 生成一个数据表
 /// </summary>
 /// <returns></returns>
 static DataTable GetTable()
 {
     try
     {
         DataTable dt = new DataTable("Characters");

         dt.Columns.Add("Column0");
         dt.Columns.Add("Column1");
         dt.Columns.Add("Column2");
         dt.Columns.Add("Column3");

         dt.Rows.Add("abc", "def", "ghi", "jkl");
         dt.Rows.Add("def", "ghi", "jkl", "mno");
         dt.Rows.Add("ghi", "jkl", "mno", "pqr");
         dt.Rows.Add("jkl", "mno", "pqr", "stu");

         Console.WriteLine("Set DataTable: " + dt.TableName);
         foreach (DataRow dr in dt.Rows)
         {
             foreach (object  obj in dr.ItemArray)
             {
                 Console.Write(obj.ToString() + " ");
             }
             Console.WriteLine();
         }
         Console.WriteLine("Mission complete!");

         return dt;
     }
     catch
     {
         return null;
     }
 }

函数：将DataTable的内容输出到DBF文件

 /// <summary>
 /// 将数据表写入到DBF文件中
 /// </summary>
 /// <param name="dt"></param>
 static void WriteToDbf(DataTable dt)
 {
     Console.WriteLine("Writing to: " + dt.TableName + ".dbf ...");

     //连接字符串
     string sConn =
         "Provider=Microsoft.Jet.OLEDB.4.0; " +
         "Data Source=" + System.IO.Directory.GetCurrentDirectory() + "; " +
         "Extended Properties=dBASE IV;";
     OleDbConnection conn = new OleDbConnection(sConn);
     conn.Open();

     try
     {
         //如果存在同名文件则先删除
         if (File.Exists(dt.TableName + ".dbf"))
         {
             Console.WriteLine("Delete file: " + dt.TableName + ".dbf ...");
             File.Delete(dt.TableName + ".dbf");
         }

         OleDbCommand cmd;

         //建立新表
         StringBuilder sbCreate = new StringBuilder();
         sbCreate.Append("CREATE TABLE " + dt.TableName + ".dbf (");
         for (int i = ; i < dt.Columns.Count; i++)
         {
             sbCreate.Append(dt.Columns[i].ColumnName);
             sbCreate.Append(" char(25)");
             if (i != dt.Columns.Count - )
             {
                 sbCreate.Append(", ");
             }
             else
             {
                 sbCreate.Append(')');
             }
         }

         Console.WriteLine("\nCreating Table ...");
         Console.WriteLine(sbCreate.ToString());
         cmd = new OleDbCommand(sbCreate.ToString(), conn);
         cmd.ExecuteNonQuery();

         //插入各行
         StringBuilder sbInsert = new StringBuilder();
         foreach (DataRow dr in dt.Rows)
         {
             sbInsert.Clear();
             sbInsert.Append("INSERT INTO " + dt.TableName + ".dbf (");
             for (int i = ; i < dt.Columns.Count; i++)
             {
                 sbInsert.Append(dt.Columns[i].ColumnName);
                 if (i != dt.Columns.Count - )
                 {
                     sbInsert.Append(", ");
                 }
             }
             sbInsert.Append(") VALUES (");
             for (int i = ; i < dt.Columns.Count; i++)
             {
                 sbInsert.Append("'" + dr[i].ToString() + "'");
                 if (i != dt.Columns.Count - )
                 {
                     sbInsert.Append(", ");
                 }
             }
             sbInsert.Append(')');

             Console.WriteLine("\nInserting lines ...");
             Console.WriteLine(sbInsert.ToString());
             cmd = new OleDbCommand(sbInsert.ToString(), conn);
             cmd.ExecuteNonQuery();
         }
     }
     catch (Exception ex)
     {
         Console.WriteLine(ex.Message);
     }

     conn.Close();
 }

Main函数中的调用

 static void Main(string[] args)
 {
     DataTable dt = GetTable(); //生成一个数据表
     WriteToDbf(dt); //将数据表输出到DBF表中

     Console.ReadLine();
7 }

运行结果
