Real Examples from EasyValidate

See actual parameter validation in action with real code from the EasyValidate test suite.

Basic Parameter Validation

Apply validation attributes to method parameters for automatic validation.

Calling Validated Methods

Choose between the original method (no validation) or the generated validation overload.

Private Method Validation

Private methods get internal validation overloads - useful for encapsulated validation logic.

Validation Process Flow

Understand how EasyValidate processes validation chains and handles errors.

Validation Chain Execution

How EasyValidate processes multiple validation attributes in sequence.

Parameter Received

Method parameter with validation attributes is processed

NotNull Check

First validation: ensures parameter is not null

NotEmpty Check

Second validation: ensures string is not empty (only if NotNull passed)

Chain Result

Returns comprehensive validation result with all checks

Error Handling Flow

What happens when validation fails at any step in the chain.

Validation Fails

Any validation attribute returns invalid result

Short-Circuit

Remaining validations are skipped for performance

Error Details

Result Returned
