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 " ".
推荐答案
这是一个不完整的问题.因此，假设您使用 TextBox 或 RichTextBox，您可以使用 TextBoxBase 中的 Lines 属性.
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;
然后您可以使用此数组并将其重新设置.
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.您不需要选择，只需使用跳过就可以了
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();
