How to acces a shader's property range from C#

I would like to make a simple UI with sliders that change properties in my shader.

I have a few properties declared in the shader like this:

name ("display name", Range (min, max)) = number

but the properties have different ranges, and the sliders are created dynamically based on the number of properties.

I would like to know if there is a way to access the range of said shader properties so that I can set a max and min value to my sliders.

No. This is not possible. You cannot access the range min and max values in Range (min, max) from C#. You have two options:

1.Hard-code the min, max values from C# in a constant variable. Make sure that they match the values in the Range (min, max) function.

2.Hard-code the min, max values from the shader itself then use HideInInspector to hide them from the Inspector since you only need to read them.

[HideInInspector]
min("Min", Float) = 0

and 

[HideInInspector]
max("Max", Float) = 1

You can now read them from C# as a float with the Material.GetFloat function. Make sure that they match the values in the Range (min, max) function.
