C# check conversion from List<string> to single string using String.Join, is possible or not? -

i have 1 list<string> length undefined, , purpose i'm converting entire list<string> string, want's check before conversion possible or not(is gonna throw out of memory exception?) can process data , continue in batch.

sample

int drc = importconfiguration.data.count; list<string> queries = new list<string>() { };  //iterate on data row generate query , execute (int drn = 0; drn < drc; drn++)//drn stands data row number {     queries.add(generate(importconfiguration.data[drn], drn));  //so here want"s check size //if it"s not possible in  next iteration i'll execute right //and emptied list again next batch      if (drn == drc - 1 || drn % 5000 == 0)     {         sqlhelper.executenonquery(connection, system.data.commandtype.text, string.join(environment.newline, queries));         queries = new list<string>() { };     } } 

since trying send large amount of text sql server instance, use sql server's streaming support write string stream go, minimizing amount of memory needed construct data send.
