◆ Random() [1/2]
Initializes a new instance of the T:System.Random class, using a time-dependent default seed value.
Definition at line 25 of file Random.cs.
◆ Random() [2/2]
| System.Random.Random |
( |
int |
Seed | ) |
|
Initializes a new instance of the T:System.Random class, using the specified seed value.
- Parameters
-
| Seed | A number used to calculate a starting value for the pseudo-random number sequence. If a negative number is specified, the absolute value of the number is used. |
Definition at line 33 of file Random.cs.
◆ Next() [1/3]
| virtual int System.Random.Next |
( |
| ) |
|
|
virtual |
Returns a non-negative random integer.
- Returns
- A 32-bit signed integer that is greater than or equal to 0 and less than F:System.Int32.MaxValue.
Definition at line 104 of file Random.cs.
◆ Next() [2/3]
| virtual int System.Random.Next |
( |
int |
minValue, |
|
|
int |
maxValue |
|
) |
| |
|
virtual |
Returns a random integer that is within a specified range.
- Parameters
-
| minValue | The inclusive lower bound of the random number returned. |
| maxValue | The exclusive upper bound of the random number returned. maxValue must be greater than or equal to minValue . |
- Returns
- A 32-bit signed integer greater than or equal to minValue and less than maxValue ; that is, the range of return values includes minValue but not maxValue . If minValue equals maxValue , minValue is returned.
- Exceptions
-
| T:System.ArgumentOutOfRangeException | minValue is greater than maxValue . |
Definition at line 128 of file Random.cs.
◆ Next() [3/3]
| virtual int System.Random.Next |
( |
int |
maxValue | ) |
|
|
virtual |
Returns a non-negative random integer that is less than the specified maximum.
- Parameters
-
| maxValue | The exclusive upper bound of the random number to be generated. maxValue must be greater than or equal to 0. |
- Returns
- A 32-bit signed integer that is greater than or equal to 0, and less than maxValue ; that is, the range of return values ordinarily includes 0 but not maxValue . However, if maxValue equals 0, maxValue is returned.
- Exceptions
-
| T:System.ArgumentOutOfRangeException | maxValue is less than 0. |
Definition at line 148 of file Random.cs.
◆ NextBytes()
| virtual void System.Random.NextBytes |
( |
byte [] |
buffer | ) |
|
|
virtual |
Fills the elements of a specified array of bytes with random numbers.
- Parameters
-
| buffer | An array of bytes to contain random numbers. |
- Exceptions
-
| T:System.ArgumentNullException | buffer is null. |
Definition at line 170 of file Random.cs.

| virtual double System.Random.NextDouble |
( |
| ) |
|
|
virtual |
Returns a random floating-point number that is greater than or equal to 0.0, and less than 1.0.
- Returns
- A double-precision floating point number that is greater than or equal to 0.0, and less than 1.0.
Definition at line 160 of file Random.cs.

( |
| ) |
|
|
protectedvirtual |
Returns a random floating-point number between 0.0 and 1.0.
- Returns
- A double-precision floating point number that is greater than or equal to 0.0, and less than 1.0.
