Methods

CheckArgument(Boolean, 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`	`Boolean` 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>(Boolean, 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`	`Boolean` 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>(Boolean, 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`	`Boolean` 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.

Remarks

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