请教！哪位朋友帮忙把C语言代码转为C#语言，谢谢！

有一个C语言的低位校验代码想转换成C#语言的没搞通。请大神帮忙转化一下，谢谢！
uint_8 ucCalculateChecksum(uint_8* pcCommandString)
        {
            uint_32 uiRunningTotal = 0;
            uint_32 i;
            /*Calculate checksum*/
            for (i = 0; i < strlen(pcCommandString); i++)
            {
                /*Add character to running total*/
                uiRunningTotal += (uint_32)pcCommandString[i];
            }
            /*Mask the lower byte and return the value to the caller*/
            return (uint_8)(uiRunningTotal & 0xFF);
        }
