保存程序配置的方法:保存到xml文件里 - C#

技术2025-01-16 15

准备:

新建一个文本文档(.txt)修改扩展名为.xml,用记事本打开写入变量,格式如下:

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

定义:

DataSet ds; //来存放数据 string path; //XML文件路径

读取方法:

private void Form1_Activated(object sender, EventArgs e) { path = Application.StartupPath+"//Settings.xml"; ds = new DataSet(); ds.ReadXml(path); //ds以表格形式读取xml的数据 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); }

保存方法:

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可读入多个表,在

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

中Settings与Settings1是dataset中的两个Table名,Settings1表有两行,text,R,G,B,为列名.
