क्योंकि मुझे ओपी के समान व्यवहार चाहिए था (एक स्ट्रिंग को बिल्कुल उसी तरह विभाजित करें जैसे कि विंडोज़ cmd करेगा) मैंने परीक्षण मामलों का एक गुच्छा लिखा और यहां पोस्ट किए गए उत्तरों का परीक्षण किया:
Test( 0, m, "One", new[] { "One" });
Test( 1, m, "One ", new[] { "One" });
Test( 2, m, " One", new[] { "One" });
Test( 3, m, " One ", new[] { "One" });
Test( 4, m, "One Two", new[] { "One", "Two" });
Test( 5, m, "One Two", new[] { "One", "Two" });
Test( 6, m, "One Two", new[] { "One", "Two" });
Test( 7, m, "\"One Two\"", new[] { "One Two" });
Test( 8, m, "One \"Two Three\"", new[] { "One", "Two Three" });
Test( 9, m, "One \"Two Three\" Four", new[] { "One", "Two Three", "Four" });
Test(10, m, "One=\"Two Three\" Four", new[] { "One=Two Three", "Four" });
Test(11, m, "One\"Two Three\" Four", new[] { "OneTwo Three", "Four" });
Test(12, m, "One\"Two Three Four", new[] { "OneTwo Three Four" });
Test(13, m, "\"One Two\"", new[] { "One Two" });
Test(14, m, "One\" \"Two", new[] { "One Two" });
Test(15, m, "\"One\" \"Two\"", new[] { "One", "Two" });
Test(16, m, "One\\\" Two", new[] { "One\"", "Two" });
Test(17, m, "\\\"One\\\" Two", new[] { "\"One\"", "Two" });
Test(18, m, "One\"", new[] { "One" });
Test(19, m, "\"One", new[] { "One" });
Test(20, m, "One \"\"", new[] { "One", "" });
Test(21, m, "One \"", new[] { "One", "" });
Test(22, m, "1 A=\"B C\"=D 2", new[] { "1", "A=B C=D", "2" });
Test(23, m, "1 A=\"B \\\" C\"=D 2", new[] { "1", "A=B \" C=D", "2" });
Test(24, m, "1 \\A 2", new[] { "1", "\\A", "2" });
Test(25, m, "1 \\\" 2", new[] { "1", "\"", "2" });
Test(26, m, "1 \\\\\" 2", new[] { "1", "\\\"", "2" });
Test(27, m, "\"", new[] { "" });
Test(28, m, "\\\"", new[] { "\"" });
Test(29, m, "'A B'", new[] { "'A", "B'" });
Test(30, m, "^", new[] { "^" });
Test(31, m, "^A", new[] { "A" });
Test(32, m, "^^", new[] { "^" });
Test(33, m, "\\^^", new[] { "\\^" });
Test(34, m, "^\\\\", new[] { "\\\\" });
Test(35, m, "^\"A B\"", new[] { "A B" });
Test(36, m, @"/src:""C:\tmp\Some Folder\Sub Folder"" /users:""abcdefg@hijkl.com"" tasks:""SomeTask,Some Other Task"" -someParam foo", new[] { @"/src:C:\tmp\Some Folder\Sub Folder", @"/users:abcdefg@hijkl.com", @"tasks:SomeTask,Some Other Task", @"-someParam", @"foo" });
Test(37, m, "", new string[] { });
Test(38, m, "a", new[] { "a" });
Test(39, m, " abc ", new[] { "abc" });
Test(40, m, "a b ", new[] { "a", "b" });
Test(41, m, "a b \"c d\"", new[] { "a", "b", "c d" });
Test(42, m, "this is a test ", new[] { "this", "is", "a", "test" });
Test(43, m, "this \"is a\" test", new[] { "this", "is a", "test" });
Test(44, m, "\"C:\\Program Files\"", new[] { "C:\\Program Files" });
Test(45, m, "\"He whispered to her \\\"I love you\\\".\"", new[] { "He whispered to her \"I love you\"." });
"अपेक्षित" मान सीधे मेरी मशीन (Win10 x64) और एक साधारण प्रिंट प्रोग्राम पर cmd.exe के साथ परीक्षण करने से आता है:
static void Main(string[] args) => Console.Out.WriteLine($"Count := {args.Length}\n{string.Join("\n", args.Select((v,i) => $"[{i}] => '{v}'"))}");
ये परिणाम हैं:

क्योंकि कोई भी उत्तर सही नहीं लगता था (कम से कम मेरे उपयोग के मामले पर आधारित) यहाँ मेरा समाधान है, यह वर्तमान में सभी परीक्षण मामलों से गुजरता है (लेकिन यदि किसी के पास अतिरिक्त (असफल) कोने के मामले हैं तो कृपया टिप्पणी करें):
public static IEnumerable<string> SplitArgs(string commandLine)
{
var result = new StringBuilder();
var quoted = false;
var escaped = false;
var started = false;
var allowcaret = false;
for (int i = 0; i < commandLine.Length; i++)
{
var chr = commandLine[i];
if (chr == '^' && !quoted)
{
if (allowcaret)
{
result.Append(chr);
started = true;
escaped = false;
allowcaret = false;
}
else if (i + 1 < commandLine.Length && commandLine[i + 1] == '^')
{
allowcaret = true;
}
else if (i + 1 == commandLine.Length)
{
result.Append(chr);
started = true;
escaped = false;
}
}
else if (escaped)
{
result.Append(chr);
started = true;
escaped = false;
}
else if (chr == '"')
{
quoted = !quoted;
started = true;
}
else if (chr == '\\' && i + 1 < commandLine.Length && commandLine[i + 1] == '"')
{
escaped = true;
}
else if (chr == ' ' && !quoted)
{
if (started) yield return result.ToString();
result.Clear();
started = false;
}
else
{
result.Append(chr);
started = true;
}
}
if (started) yield return result.ToString();
}
