首先,使用Regex.Matches
和 获取里面的{
参数}
。
string str = "req:{REQUESTER_NAME},key:{abc},act:{UPDATE},sku:{ABC123,DEF-123},qty:{10,5}";
MatchCollection matches = Regex.Matches(str,@"\{.+?\}");
string[] arr = matches.Cast<Match>()
.Select(m => m.Groups[0].Value.Trim(new char[]{'{','}',' '}))
.ToArray();
foreach (string s in arr)
Console.WriteLine(s);
输出
REQUESTER_NAME
abc
UPDATE
ABC123,DEF-123
10,5
然后用于Regex.Split
获取参数名称
string[] arr1 = Regex.Split(str,@"\{.+?\}")
.Select(x => x.Trim(new char[]{',',':',' '}))
.Where(x => !string.IsNullOrEmpty(x)) //need this to get rid of empty strings
.ToArray();
foreach (string s in arr1)
Console.WriteLine(s);
输出
req
key
act
sku
qty
现在您可以轻松地遍历参数。像这样的东西
for(int i=0; i<arr.Length; i++)
{
if(arr1[i] == "req")
//arr[i] contains req parameters
else if(arr1[i] == "sku")
//arr[i] contains sku parameters
//use string.Split(',') to get all the sku paramters and process them
}
