You can use BigInteger.TryParse Method[^]. See this:

C#

BigInteger number1;
BigInteger.TryParse("12347534159895123", out number1);
//Now converted number is stored in number1 variable

Make sure that the string contains the number within the range of an integer

Solution 6

string str1= "513442148741311"; // str1 is string value
int str2=convert.toint32(str1); or
int str2=convert.toint64(str1); // for bigint
str1 string value is converted into integer value str2.
thank u.
