c# - Getting model type from expression -


i'm trying use reflection model type. far able type of property. when tried use expression model type, i'm getting null reference property.

expression this, 

model => model.property

and in function,

//i'm passing model parameter memberexpression expbody = expression.body memberexpression; model.gettype().getproperty(expbody.member.name.tostring()));

is possible this?

memberexpression expbody = expression.body memberexpression;     expbody.type.getproperty(expbody.member.name.tostring()));

i tried this, not working.

if assume expression lambda expression parameter model, following produces behaviour expect:

expression<func<model, string>> expression = model => model.somestringproperty; type modeltype = expression.parameters[0].type; memberexpression expbody = expression.body memberexpression; propertyinfo p = modeltype.getproperty(expbody.member.name);  assert.notnull(p);

note modeltype.getproperty(expbody.member.name) unnecessary. it's preferable extract member memberexpression in order avoid ambiguity:

propertyinfo p = (propertyinfo)expbody.member;

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
