推荐答案

TextBox具有Lines属性，该属性为您提供文本框各行的字符串数组.您将需要这个和一个for循环.

创建另一个字符串数组，其长度与第一个文本框的Lines相同；然后遍历第一个文本框Lines中的每个字符串，并将第二个文本框中的行附加到该字符串.将串联的字符串存储在重复的字符串数组中的适当位置.完成对第一个文本框中的所有行的迭代之后，将串联的字符串数组分配给第三个文本框的Lines属性.

TextBoxs have a Lines property which gives you a string array of the lines of the text box. You''ll need this and a for loop.

Create another string array the same length as the first text box''s Lines; then iterate over each string in the first text box''s Lines and append the line from the second box to it. Store the concatenated string in the appropriate position in your duplicate string array. When you have finished iterating over all of the lines in the first text box, assign the concatenated string array to the third text box''s Lines property.
