Product evaluation invitation

I am glad to receive this invitation today (2016/04/12). To be honest, it is the first time for me to do a testing on product even though my major is sofeware. Perhaps it is because of this, that I am determined to spare no effort in doing this test.

Here I want to show you how to use the Spire.XLS to export data and import data.

Programming Guid

（1）Create a Project & Add Reference

（2）Using Namespace

In this project, I use the namespace as follows:

using System;
using System.Data.OleDb;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
 
using Spire.Xls;

（3）Initialization Component

private void InitializeComponent()
        {
            this.btnRun = new System.Windows.Forms.Button();
            this.btnAbout = new System.Windows.Forms.Button();
            this.label1 = new System.Windows.Forms.Label();
            this.dataGrid1 = new System.Windows.Forms.DataGrid();
            ((System.ComponentModel.ISupportInitialize)(this.dataGrid1)).BeginInit();
            this.SuspendLayout();
            //
            // btnRun
            //
            this.btnRun.Location = new System.Drawing.Point(, );
            this.btnRun.Name = "btnRun";
            this.btnRun.Size = new System.Drawing.Size(, );
            this.btnRun.TabIndex = ;
            this.btnRun.Text = "Run";
            this.btnRun.Click += new System.EventHandler(this.btnRun_Click);
            //
            // btnAbout
            //
            this.btnAbout.Location = new System.Drawing.Point(, );
            this.btnAbout.Name = "btnAbout";
            this.btnAbout.Size = new System.Drawing.Size(, );
            this.btnAbout.TabIndex = ;
            this.btnAbout.Text = "Close";
            this.btnAbout.Click += new System.EventHandler(this.btnAbout_Click);
            //
            // label1
            //
            this.label1.Font = new System.Drawing.Font("Tahoma", 9F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)()));
            this.label1.Location = new System.Drawing.Point(, );
            this.label1.Name = "label1";
            this.label1.Size = new System.Drawing.Size(, );
            this.label1.TabIndex = ;
            this.label1.Text = "I am a Label , following is DataGrid，I will show you how to export data by Spire." +
    "XLS";
            //
            // dataGrid1
            //
            this.dataGrid1.DataMember = "";
            this.dataGrid1.HeaderForeColor = System.Drawing.SystemColors.ControlText;
            this.dataGrid1.Location = new System.Drawing.Point(, );
            this.dataGrid1.Name = "dataGrid1";
            this.dataGrid1.ReadOnly = true;
            this.dataGrid1.Size = new System.Drawing.Size(, );
            this.dataGrid1.TabIndex = ;
            //
            // Form1
            //
            this.AutoScaleBaseSize = new System.Drawing.Size(, );
            this.ClientSize = new System.Drawing.Size(, );
            this.Controls.Add(this.dataGrid1);
            this.Controls.Add(this.label1);
            this.Controls.Add(this.btnAbout);
            this.Controls.Add(this.btnRun);
            this.MaximizeBox = false;
            this.MinimizeBox = false;
            this.Name = "Form1";
            this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
            this.Text = "Spire.XLS sample";
            ((System.ComponentModel.ISupportInitialize)(this.dataGrid1)).EndInit();
            this.ResumeLayout(false);
 
        }

(4)Clean up any resources being used (we can use it in other projects)

protected override void Dispose( bool disposing )
        {
            if( disposing )
            {
                if (components != null)
                {
                    components.Dispose();
                }
            }
            base.Dispose( disposing );
        }

(5)Button Click

private void btnRun_Click(object sender, System.EventArgs e)
        {
            Workbook workbook = new Workbook();
 
            workbook.LoadFromFile(@"e:\\我的课表.xls");
            //Initailize worksheet
            Worksheet sheet = workbook.Worksheets[];
 
            this.dataGrid1.DataSource =  sheet.ExportDataTable();
        }
 
        private void btnAbout_Click(object sender, System.EventArgs e)
        {
            Close();
        }

(6)Result 

It's easy to use ,isn't it?
