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();
