无法在 int64 C# 中保存 19 位数值

Question

I have a long data type and i tried to pass below value.

9947493585485901500

But i'm getting following error

Error converting value "9947493585485901500" to type 'System.Int64'. Path '[0].gId', line 1, position 108.

Can't int64 type hold the above value ? if yes.then which data type should i use for this ?

Answer 1

int64 is 64 bits. 2^64 = 18446744073709551616 which is the maximum number of unique values that can be represented by 64 bits.

int64 need also represent negative numbers, halving that to 9223372036854775808

You will need to use slightly lower numbers

Answer 2

Information about C# ranges and sizes of data types you can find in documentation . Range for int64 is -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 .
