推荐答案

这个怎么样？

How about this?

string source = "abc 10 20 10 10 10 pqr 10 20 10 10 10 wer 10 10 10 10 10 tryfhh 20 20 30 30 30";
string regExp = "[a-z]+";
Regex regx = new Regex(regExp);
MatchCollection collection = Regex.Matches(source, regExp);
for (int index = 1; index < collection.Count; index++)
{
    source = source.Replace(collection[index].Value, System.Environment.NewLine + collection[index].Value);
}
Console.WriteLine(source);

....或者使用int.TryParse作为测试继续的另一种方法当前行。

.... or another approach using int.TryParse as the test to continue the current line.

string sOutput = string.Empty;
string sInput = "abc 10 20 10 10 10 pqr 10 20 10 10 10 wer 10 10 10 10 10 tryfhh 20 20 30 30 30";
string[] sStringArray = sInput.Split(' ');
StringBuilder sb = new StringBuilder();
int iTmp = int.MinValue;

for(int i = 0; i<sStringArray.length;i++){
    if (int.TryParse(sStringArray[i], out iTmp))
    {
        //If the current array value is a number, then continue the current line ....
        sb.Append(sStringArray[i]);
        sb.Append(" ");
    }
    else
    {
        //Current array value is not a number
        if (i == 0)
        {
            // on the 1st iteration, we don't need a new line before the text value ...
            sb.Append(sStringArray[i]);
        }
        else
        {
            // on subsequent iterations, we need a new line before the text value ...
            sb.Append(Environment.NewLine);
            sb.Append(sStringArray[i]);
            sb.Append(" ");
        }
    }
}
sOutput = sb.ToString();
sb = null;

希望有所帮助。

Hope it helps.

你可以使用IndexOf。

you can use IndexOf.

int index = myString.IndexOf(' ');
int count=0;
while (index >= 0)
{
if (count == 5)
{
// take a substring of the string using index value and store it as you want
count=0;

}
    count++;
    index  = myString.IndexOf(' ', index + 1);
}
