儲存程式配置到xml檔案裡

準備:

建立一個文字文件(.txt)修改副檔名為.xml,用記事本開啟寫入變數,格式如下:

<?xml version="1.0" standalone="yes"?>
<NewDataSet>
  <Settings>
    <text></text>
    <R>255</R>
    <G>255</G>
    <B>255</B>
  </Settings>
</NewDataSet> 

定義:

DataSet ds;     //來存放資料
string path;    //XML檔案路徑

讀取方法: 

        private void Form1_Activated(object sender, EventArgs e)
        {
            path = Application.StartupPath+"//Settings.xml";
            ds = new DataSet();
            ds.ReadXml(path);                       //ds以表格形式讀取xml的資料
            textBox1.Text = ds.Tables[0].Rows[0][0].ToString();
            textBox1.BackColor =Color.FromArgb(Convert.ToInt16(ds.Tables[0].Rows[0][1])
                               ,Convert.ToInt16(ds.Tables[0].Rows[0][2])
                               , Convert.ToInt16(ds.Tables[0].Rows[0][3]));
            Activated -= new EventHandler(Form1_Activated);
        }

儲存方法:
 
        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            ds.Tables[0].Rows[0][0] = textBox1.Text;
            ds.Tables[0].Rows[0][1] = textBox1.BackColor.R;
            ds.Tables[0].Rows[0][2] = textBox1.BackColor.G;
            ds.Tables[0].Rows[0][3] = textBox1.BackColor.B;
            ds.WriteXml(path);
        } 

注意:dataset可讀入多個表,在

<?xml version="1.0" standalone="yes"?>
<NewDataSet>
  <Settings>
    <text></text>
    <R>255</R>
    <G>255</G>
    <B>255</B>
  </Settings>
  <Settings2>
    <text></text>
    <R>255</R>
    <G>255</G>
    <B>255</B>
  </Settings2>
  <Settings2>
    <text></text>
    <R>255</R>
    <G>255</G>
    <B>255</B>
  </Settings2>
</NewDataSet> 

 

中Settings與Settings1是dataset中的兩個Table名,Settings1表有兩行,text,R,G,B,為列名.
