To learn how to use resource ~, this function should have a lot of information can be found, you will have to demand is emerged from the first N same characters began to intercept to the end of the string, need to have is this character when the NTH appear in the string to be digits, and then use the substring interception, below is for digits have a method, the incoming string is needed, special characters, how many times a
Public int findNumber (String STR, String letter, int num) {
Int I=0;
Int m=0;
Char c=new String (letter). CharAt (0);
Char [] ch=STR. ToCharArray ();
for(int j=0; jIf (ch [j]==c) {
I++;
If (I==num) {
M=j;
break;
}
}
}
Return m;

According to the big though moral emperor supreme instructions, I won't tell you the following code (because according to the moral standard of big however, make a mockery of what you don't know the uri is the following code)

 Uri Uri=new Uri (" http://127.0.0.1:1111/Upload/20200417/aaa9754-4865-808e-94738f636b6c.png ");
