推荐答案

Linq解决方案：

Linq solution:

string[] filecontent = File.ReadAllLines(@"FullTextFileName");
var lines = filecontent.Where(x=>!string.IsNullOrWhiteSpace(x)).Select(x=>x);

注意：OriginalGriff [ ^ ]提到（在问题的评论中）上面的代码不会消除空白行。我测试了它，它工作正常。如果上面的代码有问题，请告诉我。我想知道文本编码。这可能是麻烦的原因。



谢谢你，OriginalGriff，指出我想要获得特定的输出。



这是一个想法：

Note: OriginalGriff[^] mentioned (in the comment to the question) that above code does not eliminate blank lines. I tested it and it works fine. Please, let me know if there is a problem with above code. I'm wondering about text coding. It might be the reason of troubles.

Thank you, OriginalGriff, for pointing me that OP wanted to get specific output.

Here is an idea:

string[] filecontent = { "ABC", "D", "", "EF", "G", "", "HIJ", "K", "LM"};
var lines = filecontent.Where(x=>!string.IsNullOrEmpty(x))
            .Select((x, ind) => new{line=(string)x, index=(int)ind+1})
            .Aggregate("", (a, b) => a += (((b.index+1) % 2==0) ? " " : "") + b.line).Split(' ').Skip(1);

结果：

Result:

ABCD
EFG
HIJK
LM

尝试：

Try:

string[] inp = { "ABC", "D", "", "EF", "G" };
List<string> outp = new List<string>();
StringBuilder sb = new StringBuilder();
foreach (string s in inp)
    {
    if (string.IsNullOrWhiteSpace(s))
        {
        if (sb.Length > 0) outp.Add(sb.ToString());
        sb = new StringBuilder();
        }
    else
        {
        sb.Append(s);
        }
    }
if (sb.Length > 0) outp.Add(sb.ToString());</string></string>
