Cannot convert type 'System.Collections.Generic.List<CodeGenerator.Models.ColumnInfo>' to 'System.Collections.Generic.List<CodeGenerator.Models.ColumnInfo>'

Hi, @foreach (var col in ((List<ColumnInfo>)Model.FormFields).Where(c => !c.IsIdentity))

err:
Cannot convert type 'System.Collections.Generic.List<CodeGenerator.Models.ColumnInfo>' to 'System.Collections.Generic.List<CodeGenerator.Models.ColumnInfo>'

What is the reason for this? I only know a little English. Sorry about that.

    var parts = input.Split('_', '-', ' ');
    return string.Concat(parts.Select(p => char.ToUpper(p[0]) + p[1..].ToLower()));
}
