Erro 2 Não é possível converter implicitamente o tipo ‘float []’ para ‘string’

Estou tentando capturar os valores de uma musica que depois sao enviados para um visualizer. O que estou a tentar fazer e de capturar os valores recebidos e transformar los em numeros e com esses numeros fazer outro tipo de visualizador de som , como por exemplo desenhar alguns pixeis randomizado em cores en um panel. O codigo que uso foi tirado aqui Codeproject este e o codigo que da o erro o label e so para efeitos de debug

void source_ProcessData(float[] data)     {         soundVisualizer1.AppendData(data);         soundVisualizer1.TriggerRedraw();            float value = data;         string str1 = value.ToString();          label1.Text =str1;     } 

Este e o codigo que estou usando

C# converter Array para inserção no banco [pendente]

Tenho um Array, alguns dos valores desse array será adicionado como float outros como int, minha duvida é a seguinte, como eu posso converter apenas um array não a lista toda?

Eu teria que criar uma variável para receber esse valor e converter? ou teria um jeito mais simples?

while (Arquivo.Peek() != -1) {      var strLinha = Arquivo.ReadLine().Split('|');      arrValores[0] = strLinha[1];      arrValores[1] = strLinha[2];      arrValores[2] = strLinha[3];      arrValores[3] = strLinha[4];      cmd.CommandText = string.Format("INSERT INTO [dbo].[123] VALUES ('{0}','{1}','{2}','{3}')", strLinha[1], strLinha[2], strLinha[3], strLinha[4]);      cmd.ExecuteNonQuery(); }

Como converter 39 horas para o tipo ‘TIME’

Para realizar certa tarefa, contabilizo em meu sistema o tempo gasto da respectiva tarefa.

Hoje me deparei com o seguinte:

Data Inicial: 17/12/2018 16:49:14 Data Final: 19/12/2018 08:02:58

totalizando: 2362,29 minutos.

Converto para decimal: (2362,29 / 60) = 39,3716

Porém preciso converter esse valor (39,3716) para o formato TIME

Porém, segundo documentação hora (Transact-SQL)

O intervalo permitido é de: 00:00:00.0000000 a 23:59:59.9999999

Teria algum outro modo de representar esse valor com o tipo TIME?

Obs: Sei que, o valor 39,3716, representa 39 horas e 50 minutos, porém preciso que a coluna seja do time TIME, caso contrario, poderia definir a coluna como VARCHAR e apresentar o valor 39:50.
