Comment améliorer ce code en utilisant C#

Question

Possible en double:
Is there a simpler way to do this if statement in C#

J'ai ce code:

while ((txtSource.Text[startPos].ToString() == " ") || 
     (txtSource.Text[startPos].ToString() == ",") || 
     (txtSource.Text[startPos].ToString() == "."))) 
     { 
      // do something 
     } 

est-il possible de faire ce qui précède comme pour instance:

while (!txtSource.Text[startPos].ToString() in (" ",",",".")) 

Answer 1

while ((new char[] {' ', ',', '.'}).Contains(txtSource.Text[startPos])) 

Answer 2

LINQ Any() aide:

string text = "some text"; 
char[] controlChars = { ' ', ',', '.' }; 
int index = 1; 
bool passed = controlChars.Any(c => c == text[index]); 

Answer 3

string[] SearchList = {" ",",","."}; 

while (SearchList.Contains(txtSource.Text[startPos].ToString())) 
{ 
    // Do Something 
} 

Answer 4

private static bool IsStopChar(char c) 
{ 
    switch (c) 
    { 
    case ' ': 
    case ',': 
    case '.': 
     return false; 
    default: 
     return true; 
    } 
} 

//... 

    while (!IsStopChar(txtSource.Text[startPos])) 
    { 
    //... 
    } 

Avec cette solution, vous éviter la collecte itération, l'allocation de mémoire, l'initialisation, ... cas reste facile Modification.
