String vs StringBuilder
At what point does using a StringBuilder become insignificant or an overhead?
尽可能简单明了，我有这个方法 1:
cmd2.CommandText = ("insert into " + TableName + " values (" + string.Join(",", insertvalues) + ");");
我想知道如果我这样做，方法 2 是否更快:
StringBuilder sb2 = new StringBuilder();
sb2.Append("insert into ");
sb2.Append(TableName);
sb2.Append(" values (");
sb2.Append(string.Join(",", insertvalues));
sb2.Append(");");
cmd2.CommandText = sb2.ToString();
