使用可从Excel读取的C#代码创建.DBF(VFP与否)

Question

语言:C#,系统:Windows7,Excel 2007

我想从一些数据创建.DBF,我想从Excel 2007打开它.它可以是dBase或foxpro.我目前正在使用FoxPro9(顺便说一句,这段代码来自互联网):

 OleDbConnection con = new OleDbConnection("Provider=VFPOLEDB.1;Data Source=C:\\Temp\\;");
            con.Open();
            OleDbCommand cmd1 = new OleDbCommand("Create Table TestDBF (Field1 I, Field2 C(10))", con);
            OleDbCommand cmd2 = new OleDbCommand("Insert Into TestDBF Values (1, 'Hello')", con);
            OleDbCommand cmd3 = new OleDbCommand("Insert Into TestDBF Values (2, 'World')", con);
            cmd1.ExecuteNonQuery();
            cmd2.ExecuteNonQuery();
            cmd3.ExecuteNonQuery();
            con.Close();

这会生成我可以在DbfViewer中打开的文件,但是,我无法在Excel 2007中打开它,也不能在我拥有的某些应用程序中使用.我可以使用DbfViwer手动将FoxPro .dbf转换为dbaseIII dbf,但我希望它是自动的.

有任何想法吗？

提前致谢

这是一个小的控制台应用程序,它将使用CREATE TABLE SQL语法创建DBF,然后将其复制到可以在Excel中打开的FoxPro DBF文件格式的先前版本.

static void Main(string[] args)
{
    Console.WriteLine("Starting program execution...");

    string connectionString = @"Provider=VFPOLEDB.1;Data Source=C:\YourDirectory\";

    using (OleDbConnection connection = new OleDbConnection(connectionString))
    {
        using (OleDbCommand scriptCommand = connection.CreateCommand())
        {
            connection.Open();

            string vfpScript = @"Create Table TestDBF (Field1 I, Field2 C(10))
                                USE TestDBF
                                COPY TO OpensWithExcel TYPE Fox2x
                                USE";

            scriptCommand.CommandType = CommandType.StoredProcedure;
            scriptCommand.CommandText = "ExecScript";
            scriptCommand.Parameters.Add("myScript", OleDbType.Char).Value = vfpScript;
            scriptCommand.ExecuteNonQuery();
        }
    }

    Console.WriteLine("End program execution...");
    Console.WriteLine("Press any key to continue");
    Console.ReadLine();
}

}
