一共有TextBox button ComboBox三個(gè)控件 、在Textbox里輸入內(nèi)容、點(diǎn)添加 、就把內(nèi)容添加到了ComboBox中 、 內(nèi)容需要寫(xiě)入到XML或者記事本、下次重啟軟件的時(shí)候添加的內(nèi)容才會(huì)存在 、請(qǐng)問(wèn)我該如何把我輸入的內(nèi)容添加到XML或者記事本中？
隨便寫(xiě)了個(gè)代碼，通過(guò)記錄文本實(shí)現(xiàn)的。

string line;
while ((line = sr.ReadLine()) != null)
{
comboBox1.Items.Add(line);
}
sr.Close();
}
else
{

}
}
private void button1_Click(object sender, EventArgs e)
{
if (textBox1.Text != "")
{
GC.Collect();
StreamWriter writeline = new StreamWriter(@"c:\2.txt", true, Encoding.GetEncoding("GB2312"));
writeline.Write(textBox1.Text + "\r\n");
writeline.Flush();
writeline.Close();
comboBox1.Items.Add(textBox1.Text);
textBox1.Text = "";
}
else
{
MessageBox.Show("請(qǐng)輸入內(nèi)容");
}
}
}
}
