private void Func(DataRow[] DtRowTemp)
{
    DataRow[] DT2 ;
    DT2 = DtRowTemp; // It work and DTRowTemp value has set to DT2

    // above code don't work
    DT2[0].ItemArray[3] = 3;   // Last Value Was 2 and I want to change this value to 3

Answer 1

使用ItemArray属性可以获取或设置ENTIRE数组,而不是单个值.

用它来设置第四项:

 DT2[0][3] = 3;
