Methods

CheckArgument(bool, string, string)

public static void CheckArgument(bool condition, string paramName, string message)

Checks that given argument-based condition is met, throwing an ArgumentException otherwise.

Parameters
Name	Description
condition	bool The (already evaluated) condition to check.
paramName	string The name of the parameter whose value is being tested.
message	string The message to include in the exception, if generated. This should not use interpolation, as the interpolation would be performed regardless of whether or not an exception is thrown.

CheckArgument<T>(bool, string, string, T)

public static void CheckArgument<T>(bool condition, string paramName, string format, T arg0)

Checks that given argument-based condition is met, throwing an ArgumentException otherwise.

Parameters
Name	Description
condition	bool The (already evaluated) condition to check.
paramName	string The name of the parameter whose value is being tested.
format	string The format string to use to create the exception message if the condition is not met.
arg0	T The argument to the format string.

Type Parameter
Name	Description
T

CheckArgument<T1, T2>(bool, string, string, T1, T2)

public static void CheckArgument<T1, T2>(bool condition, string paramName, string format, T1 arg0, T2 arg1)

Checks that given argument-based condition is met, throwing an ArgumentException otherwise.

Parameters
Name	Description
condition	bool The (already evaluated) condition to check.
paramName	string The name of the parameter whose value is being tested.
format	string The format string to use to create the exception message if the condition is not met.
arg0	T1 The first argument to the format string.
arg1	T2 The second argument to the format string.

Type Parameters
Name	Description
T1
T2

CheckArgumentRange(int, string, int, int)

public static int CheckArgumentRange(int argument, string paramName, int minInclusive, int maxInclusive)

Checks that the given argument value is valid.

Parameters
Name	Description
argument	int The value of the argument passed to the calling method.

minInclusive	int The smallest valid value.
maxInclusive	int The largest valid value.

Returns
Type	Description
int	argument if it was in range

Remarks

Note that the upper bound (maxInclusive) is inclusive, not exclusive. This is deliberate, to allow the specification of ranges which include MaxValue.

Exceptions
Type	Description
ArgumentOutOfRangeException	The argument was outside the specified range.
