问题描述
我需要将长句子分成保留整个单词的部分.每个部分都应该给出最大字符数(包括空格、点等).例如:
I need to split long sentence into parts preserving whole words. Each part should have given maximum number of characters (including space, dots etc.). For example:
int partLenght = 35;
string sentence = "Silver badges are awarded for longer term goals. Silver badges are uncommon."
输出:
1 part: "Silver badges are awarded for"
2 part: "longer term goals. Silver badges are"
3 part: "uncommon."
推荐答案
试试这个:
static void Main(string[] args)
{
int partLength = 35;
string sentence = "Silver badges are awarded for longer term goals. Silver badges are uncommon.";
string[] words = sentence.Split(' ');
var parts = new Dictionary<int, string>();
string part = string.Empty;
int partCounter = 0;
foreach (var word in words)
{
if (part.Length + word.Length < partLength)
{
part += string.IsNullOrEmpty(part) ? word : " " + word;
}
else
{
parts.Add(partCounter, part);
part = word;
partCounter++;
}
}
parts.Add(partCounter, part);
foreach (var item in parts)
{
Console.WriteLine("Part {0} (length = {2}): {1}", item.Key, item.Value, item.Value.Length);
}
Console.ReadLine();
}
