如何在C＃代码中解决多余的空格问题？

Question

I get an error when I get the numbers from a .txt file when I use extra spaces between numbers. Example: 56 (space) (space) (space) 45 (space) (space) 6 (space) (space) (space) (space) (space) 2 789

There is no problem when i use 1 space between numbers. Example: 56 45 6 2 789

for (int i = 0; i < count; i++)
{
    string[] temp2;
    temp2 = ReadText[i].Split(' ');
    for (int a = 0; a < temp2.Length; a++)
    {
        Value[ValueCount] = float.Parse(temp2[a]);
        ValueCount++;
    }
}

I'd expect normally works, but there's something wrong, and I don't get it.

You can use TryParse to help you

for (int i = 0; i < count; i++)
{
    string[] temp2;
    temp2 = ReadText[i].Split(' ');
    for (int a = 0; a < temp2.Length; a++)
        if (float.TryParse(temp2[a], out Value[ValueCount]))
            ValueCount++;
}

You can also try StringSplitOptions

for (int i = 0; i < count; i++)
{
    string[] temp2;
    temp2 = ReadText[i].Split(new char[] {' '}, StringSplitOptions.RemoveEmptyEntries);
    for (int a = 0; a < temp2.Length; a++)
        Value[a] = float.Parse(temp2[a]);
}
