MethodQuery

MethodQuery¶

Find methods on a type.

See also: Queries Overview | TypeQuery | ParameterQuery

// Static factory
var methods = MethodQuery.From(typeSymbol)
    .ThatAreAsync()
    .ThatArePublic()
    .ReturningTask()
    .GetAll();

// Extension method (preferred)
var handlers = typeSymbol.QueryMethods()
    .WithNameEndingWith("Handler")
    .WithParameterCount(1)
    .GetAll();

Factory Methods¶

Method	Description
`From(ITypeSymbol)`	Query methods on a type
