这里有2种方式来做到这一点:方法1是更安全的选择
1。
protected void Button1_Click(object sender, EventArgs e)
{
string a = TextBox1.Text;
string[] b = a.Split(new string[] { System.Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries);
StringBuilder sb = new StringBuilder();
foreach (string ss in b)
{
sb.Append("ABC");
sb.Append(ss);
sb.Append(System.Environment.NewLine);
}
TextBox1.Text = sb.ToString();
}
（2）
protected void Button1_Click(object sender, EventArgs e)
{
string a = TextBox1.Text;
string[] b = a.Split(new string[] { System.Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries);
TextBox1.Text = string.Empty;
foreach (string ss in b)
{
TextBox1.Text += ("ABC" + ss + System.Environment.NewLine);
}
}
