有没有在C＃中优雅的方式从多行文本框的开始删除多行文本？我使用Microsoft Visual C＃2008 Express Edition的。

Is there a graceful way in C# to delete multiple lines of text from the beginning of a multiline textbox? I am using Microsoft Visual C# 2008 Express Edition.

在我的应用程序中的多行文本框被禁用（即它只能由应用程序本身可编辑），每行以一个\r\\\
。

EDIT - Additional Details The multiline textbox in my application is disabled (i.e. it is only editable by the application itself), and every line is terminated with a "\r\n".

推荐答案

这是一个不完整的问题。因此，假设您正在使用文本框或RichTextBox中您可以使用href=\"http://msdn.microsoft.com/en-us/library/system.windows.forms.textboxbase.lines.aspx\"> Lines属性发现。

This is an incomplete question. So assuming you are using either TextBox or RichTextBox you can use the Lines property found inTextBoxBase.

//get all the lines out as an arry
string[] lines = this.textBox.Lines;

您就可以与这一类工作，并设置了回去。

You can then work with this array and set it back.

  this.textBox.Lines= newLinesArray;

这可能不是最优雅的方式，但它会删除第一行。
编辑：你不需要选择，只是用跳跃将被罚款

This might not be the most elegant way, but it will remove the first line. you don't need select, just using skip will be fine

    //number of lines to remove from the beginning
    int numOfLines = 30; 
    var lines = this.textBox1.Lines;
    var newLines = lines.Skip(numOfLines);

    this.textBox1.Lines = newLines.ToArray();
