string a = "A";

you could use Split(char c)that will give you back an array of sub strings seperated by the ~ symbol.
你可以使用Split(char c)它会给你一个string由 ~ 符号分隔的 sub 数组。
string src = "A~B~C~D";
string [] splits = src.Split('~');
obviously though, unless you know the length of your string/words in advance you won't be able to arbitrarily put them in their own variables. but if you knew it was always 4 words, you could then do
显然，除非您事先知道字符串/单词的长度，否则您将无法随意将它们放入自己的变量中。但如果你知道它总是 4 个词，你就可以做
string a = splits[0];
string b = splits[1];
string c = splits[2];
string d = splits[3];

Try this one. It will split your string with all non-alphanumeric characters.
试试这个。它会将您的字符串与所有非字母数字字符分开。
string s = "A~B~C~D";
string[] strings = Regex.Split(s, @"\W|_");

Please try this
请试试这个
string src = "A~B~C~D"
//
// Split string on spaces.
// ... This will separate all the words.
//
string[] words = src .Split('~');
foreach (string word in words)
{
Console.WriteLine(word);
}

string src = "A~B~C~D";
string[] letters = src.Split('~');
foreach (string s in letters)
{
//loop through array here...
}

You can do:
你可以做：
string src = "A~B~C~D";
string[] strArray = src.Split('~');
string a = strArray[0];
string b = strArray[1];
string c = strArray[2];
string d = strArray[3];

Consider...
考虑...
string src = "A~B~C~D";
string[] srcList = src.Split(new char[] { '~' });
string a = srcList[0];
string b = srcList[1];
string c = srcList[2];
string d = srcList[3];

string words[]=Regex.Matches(input,@"\w+")
.Cast<Match>()
.Select(x=>x.Value)
.ToArray();
\wmatches a single word i.e A-Z or a-z or _or a digit
\w匹配单个单词，即 AZ 或 az 或_或数字
+is a quantifier which matches preceding char 1 to many times
+是一个量词，它匹配前面的字符 1 多次

I like to do it this way:
我喜欢这样做：
List<char> c_list = new List<char>();
string src = "A~B~C~D";
char [] c = src.ToCharArray();
foreach (char cc in c)
{
if (cc != '~')
c_list.Add(cc);
}
