同样的代码为什么编译成DLL文件以后引用就报错呢？求高手解惑。
我是新手代码如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace matrix
{
public class Matrix
{
public double[,] ReverseMatrix(double[,] dMatrix, int Level)
{
double dMatrixValue = MatrixValue(dMatrix, Level);
if (dMatrixValue == 0)
return null;
double[,] dReverseMatrix = new double[Level, 2 * Level];
double x, c;
// Init Reverse matrix
for (int i = 0; i < Level; i++)
{
for (int j = 0; j < 2 * Level; j++)
{
if (j < Level)
dReverseMatrix[i, j] = dMatrix[i, j];
else
dReverseMatrix[i, j] = 0;
}
dReverseMatrix[i, Level + i] = 1;
}
for (int i = 0, j = 0; i < Level && j < Level; i++, j++)
{
if (dReverseMatrix[i, j] == 0)
{
int m = i;
for (; dMatrix[m, j] == 0; m++)
;
if (m == Level)
return null;
else
{
// Add i-row with m-row
for (int n = j; n < 2 * Level; n++)
dReverseMatrix[i, n] += dReverseMatrix[m, n];
}
}
// Format the i-row with "1" start
x = dReverseMatrix[i, j];
if (x != 1)
{
for (int n = j; n < 2 * Level; n++)
if (dReverseMatrix[i, n] != 0)
dReverseMatrix[i, n] /= x;
}
// Set 0 to the current column in the rows after current row
for (int s = Level - 1; s > i; s--)
{
x = dReverseMatrix[s, j];
for (int t = j; t < 2 * Level; t++)
dReverseMatrix[s, t] -= (dReverseMatrix[i, t] * x);
}
}
// Format the first matrix into unit-matrix
for (int i = Level - 2; i >= 0; i--)
{
for (int j = i + 1; j < Level; j++)
if (dReverseMatrix[i, j] != 0)
{

}

{

{

;
if (m == Level)
return 0;
else

{

}

}
