private void addlog(string str) { string strTxtLog = textBoxLog.Text; textBoxLog.Text = "[" + DateTime.Now.ToString() + "]" + str + "\r\n" + strTxtLog; dellog(); } private void dellog() { //实现textBoxLog行数超过100行自动删除100行以后的数据。 }
int limitLineCount = 2; if (textBox1.Lines.Count() > limitLineCount) { this.textBox1.Text = string.Join("\r\n", this.textBox1.Lines.Take(limitLineCount)); }
------解决方案--------------------
int count = this.richTextBox1.Lines.Length;
if (count > 2)
{
string[] str = this.richTextBox1.Lines;
this.richTextBox1.Lines = new string[] { str[0], str[1] };
}
楼上this.textBox1.Lines.Take(limitLineCount) Take 函数 是 4.0编译器的?
