Changing material color or texture to a material

[morenostef]

Hi. I'm experimenting with materials in c#. I'd like to replace a material of an imported model with a new material runtime.If the material is already created among the assets,no problem loading it . The problems arise when i create a material runtime and i must change color or texture. I followed the manual suggestion below,but there is no "material.Parameters" and,obviously i get errors.
Are there solutions ?
/////////////////////////
// Create a material (eg with red diffuse color).
var materialDescription = new MaterialDescriptor
{
Attributes =
{
DiffuseModel = new MaterialDiffuseLambertModelFeature(),
Diffuse = new MaterialDiffuseMapFeature(new ComputeColor { Key = MaterialKeys.DiffuseValue })
}
};
var material = Material.New(GraphicsDevice, materialDescription);
material.Parameters[0].Set(MaterialKeys.DiffuseValue, Color.Red);
model.Materials.Add(0, material);
/////////////////////////////////////

Can you clarify where you got this example?

The code should be

material.Passes[0].Parameters.Set(MaterialKeys.DiffuseValue, Color.Red);

I found the example in the stride 4.2 manual
