在SqlParameter中使用DateTime存储过程,格式错误

DateTime dateTime = new DateTime(2022, 1, 1, 12, 0, 0);
string dateTimeString = dateTime.ToString("yyyy-MM-dd HH:mm:ss");

SqlCommand command = new SqlCommand("MyStoredProcedure", connection);
command.CommandType = CommandType.StoredProcedure;

SqlParameter parameter = new SqlParameter("@DateTimeParam", SqlDbType.DateTime);
parameter.Value = dateTimeString;
command.Parameters.Add(parameter);

CREATE PROCEDURE MyStoredProcedure
    @DateTimeParam NVARCHAR(MAX)
AS
BEGIN
    DECLARE @DateTimeValue DATETIME
    SET @DateTimeValue = CONVERT(DATETIME, @DateTimeParam, 120)

    -- 存储过程的其他逻辑
END
