Custom extension method to simplify LINQ to SQL statement

Question

I have a snippet of LINQ code that I need to use in a lot of queries

let catchmentId = Convert.ToInt32(
        phy.PhysicalProperty_binData.Substring(offset + 3         


        

Answer 1

Wrong language (sorry) here it is in F# if people need.

let catchmentId =  
    // Curry in invariant components.
    let newSubstr end = 
        phy.PhysicalProperty_binData.Substring(offset + end, 1)
    Convert.ToInt32(
        newSubstr 3 +
        newSubstr 2 + 
        newSubstr 1 +
        newSubstr 0)
