Migration trobules upgrading from vb6 to vb.net

I want to upgrade Vb5 code to Vb.net but I don't know how to upgrade this command strMsgDtl and vbCrLf are str开发者_如何学编程ing:

strMsgDtl = strMsgDtl & String(75, "-") & vbCrLf

What does the following command mean??

String(75, "-")

---

String(75,"-") creates a string 75 characters long, made of the "-" character.

VB.Net equivalent would be New String("-", 75)
